Rory O'Connor: The Architecture of Rhythm in Tycho

There is a moment in any live Tycho performance when something shifts. The synthesizers build, the guitar lines layer over one another, the visual projections cast their light across the crowd — and then a kick drum lands, a snare cracks, and suddenly the music stops being something you experience through headphones and becomes something you feel in your sternum. That moment belongs to Rory O’Connor. He has been making it happen, night after night, since 2012.

O’Connor’s position in the Tycho project is one of the more unusual in contemporary music. He is the drummer in a project that, for its first decade, had no drummer. He plays acoustic instruments in a context designed around synthesizers and samples. He executes rhythmic patterns that began as programmed loops and must be translated, live and in real time, into something both technically identical to the recording and emotionally alive in ways that no sequencer can replicate. And he is, increasingly, not just a performer executing Hansen’s vision but a compositional partner whose recorded drumming serves as the raw material from which albums are built before a single melody has been written.

To understand what O’Connor brings to Tycho, you have to understand where he came from, what it took for him to end up in Hansen’s basement in San Francisco, and what the music sounded like before he arrived — and after.

Westfield, Massachusetts: A Musical Household in the Berkshire Foothills

Rory O’Connor grew up in Westfield, Massachusetts, a mid-size city in the westernmost part of the state, in the foothills of the Berkshire Mountains. It is not a place people typically associate with electronic music, or with any particular musical scene. But O’Connor’s household was a different matter: his father was a drummer, his mother was a pianist, and the combination of these two instruments — one rhythmic, one harmonic — shaped his musical intuitions from childhood in ways that would remain directly relevant to his work decades later.

He was largely self-taught. He never had private lessons. He arrived at the drums the way many self-taught musicians arrive at their instrument: through proximity, imitation, and an early conviction that this was simply what he was going to do. By the time he was in his early teens, music was not a hobby or an interest but an orientation, the primary lens through which he understood his own life.

One detail O’Connor has shared reveals something specific about his cast of mind: in seventh grade, he got a paper route specifically to save up enough money to buy a four-track cassette recorder. This was not a kid who wanted to play drums. This was a kid who wanted to record things, to capture sounds and layer them and hear what they became. A paper route to fund a four-track recorder is, when you trace it forward, a direct precursor to the Nitemoves albums written in the back seats of tour vans, to the Rory Library of drum loops that became the rhythmic foundation of a Grammy-nominated album. The compulsion to document and arrange was there from the beginning.

He graduated from Westfield High School in 2003. His music director there, a man named Pat Kennedy, served as a crucial mentor — the kind of figure who appears in the biographies of many musicians, the teacher who sees something in a student before the student is fully certain it exists and commits to developing it. O’Connor has spoken about Kennedy’s influence with genuine warmth, the recognition that institutional musical education can matter even when the formal curriculum itself has little to do with what the student will eventually become.

From his father’s kit, O’Connor had absorbed an understanding of rhythm as something physical and immediate. From his mother’s piano, he had absorbed an understanding of melody as architecture, of notes arranged over time as structural objects. Together, these influences produced a musician who would eventually be described by his bandleader as “a turn-key solution” — not because his skills were generic and interchangeable, but precisely because they were so specific to what was needed.

He briefly attended college with a focus on music before making the decision that many musicians of his generation made: that the industry had less to do with formal education than with being in the right rooms at the right times, and that the only way to be in those rooms was to go where they were. He dropped out, and he moved to New York.

Brooklyn and the Ghostly International Network: Building a Career in the Void Between Electronic and Live

O’Connor spent approximately six years in Brooklyn, which, in the mid-to-late 2000s, was one of the most generative musical environments in the world for exactly the kind of music he was drawn to. The borough at that time was producing a distinct cultural formation: artists and producers who had grown up on electronic music — who had internalized its sounds, its aesthetics, its relationship with programmed rhythm — but who were also drawn to the visceral, irreducibly human quality of live performance. They wanted both. They wanted music that could exist as a headphone experience and also as a stage event where bodies were visibly producing the sound.

This was, and remains, a genuinely difficult thing to achieve. The history of electronic music is littered with attempts to translate studio productions into live contexts that either feel underpowered (two people behind laptops, nothing moving) or overcorrected (a full rock band playing over backing tracks, losing the electronic character entirely). The musicians who found answers to this problem in Brooklyn’s late-2000s scene were not just useful performers — they were solving one of the central unsolved problems in contemporary music.

O’Connor embedded himself in this community. His primary professional network converged on the orbit of Ghostly International, the Ann Arbor-based independent label that had become one of the most coherent curatorial voices in American independent electronic music. Ghostly’s aesthetic — design-conscious, emotionally warm, committed to a particular relationship between visual identity and sonic character — attracted a specific kind of musician, and O’Connor found himself among them in Brooklyn’s informal, show-going, studio-sharing ecosystem.

The label connection was not incidental. Ghostly had been Scott Hansen’s home since the mid-2000s, and the Ghostly community was therefore the social network most likely to produce a direct connection to Hansen. But that connection was still years away. First, O’Connor needed to establish himself in the specific role he would eventually fill.

The decisive break came through Com Truise, the project of Seth Haley, another Ghostly International artist. Haley’s music — dense, synth-heavy, rhythmically propulsive, rooted in an elaborate retro-futurist aesthetic — needed exactly what Hansen’s music needed: a live drummer who could translate programmed beats into organic performance without losing the electronic character. When Com Truise needed a drummer for the Galactic Melt tour in 2011 and 2012, O’Connor was the recommended candidate. He already knew the album intimately. His performance in that role was decisive — not merely competent, but precisely calibrated to what the material required. Haley’s music needed someone who understood what programmed drums were trying to do and could do that thing with a physical kit in a room. O’Connor understood it.

His work on the Com Truise tour is what led, through the mutual networks of the Ghostly community, to the phone call from Scott Hansen.

The Audition: Several Hours in a San Francisco Basement

The story of O’Connor joining Tycho has the structure of a good origin myth because it contains the elements that origin myths are supposed to contain: the unexpected call, the leap of faith, the test that determines everything.

After Tycho’s second European tour, Hansen flew O’Connor to San Francisco to audition. There were no specific pieces to prepare, no formal repertoire to demonstrate. The audition took the form of a several-hour jam session in Hansen’s basement — two musicians feeling out whether they spoke the same musical language, whether the instincts of one matched the instincts of the other in ways that would make sustained collaboration possible.

The audition was not a neutral encounter. O’Connor had been a fan of Tycho’s music for over a decade before that afternoon — he knew the records, had listened to them with genuine investment, understood them as a listener before he was asked to understand them as a performer. This mattered. When Hansen later described O’Connor as a “turn-key solution,” the phrase captured something important: the familiarity O’Connor brought to the material meant that the initial period of orientation was minimal. He could step into the role and immediately begin improving the music rather than spending months simply learning how to fit inside it.

What Hansen was looking for was specific. He had been performing Tycho music solo — laptop, keyboard, projections — and had arrived at a clear frustration with the form. As he described it, solo laptop performance is essentially DJing your own music: the sounds are produced by the machine, the human is operating it rather than generating it, and the audience can see the gap. He needed bodies on stage, hands on instruments, visible human effort translating electronic abstraction into something physically present. He needed a drummer who could make the beats he had programmed feel as alive as they sounded in his head.

The challenge was not simply that he needed a drummer. He needed a specific kind of drummer: someone who understood electronic music well enough to honor its character, who had the technical control to execute programmed patterns without reducing them to mechanical repetition, and who had enough musical personality to add the human variability that makes live performance worth attending. That combination was rare enough that when O’Connor walked into his basement and demonstrated it over several hours, Hansen recognized it immediately.

O’Connor joined the band during the Dive tour in 2011 and 2012. He has been Tycho’s drummer ever since.

The First Album Cycle: What Awake Became Because of O’Connor

Rory O’Connor did not play on Dive, the 2011 album that established Tycho’s reputation. He joined for the Dive tour, after the record was finished. But what happened during that touring cycle changed the project’s direction permanently.

Hansen and Brown had spent years building Tycho’s sound in studios and home setups. The Dive material was dense, layered, carefully constructed — the product of a meticulous solo producer’s way of working, assembled from samples and loops and programmed beats, filtered through an elaborate analog signal chain until it glowed with a particular warmth. It was, in many respects, already complete.

And then Rory O’Connor started playing it live, and Hansen heard what it could be.

The energy of the live performances exceeded what the recordings had captured. A drum kit behind the music changed its physical character — the beats that were tight and digital in the studio became something you felt in your ribcage when O’Connor played them. The way he moved through the material, his natural micro-inflections, the small rushes and retreats that no sequencer can program, gave the songs a presence they had not quite had before. Hansen recognized this. He recognized it so clearly that when it came time to make the next record, he made a fundamental decision: this time, Rory plays from the beginning.

The process for Awake, released in 2014, reflected this decision. Hansen and Brown began the writing sessions in the now-familiar Lake Tahoe cabin retreat — removing themselves from the city to work in isolation, building structural and melodic foundations over several weeks. But O’Connor was brought into the process for the Santa Cruz sessions that followed, and the songs were built around his live drum performances rather than having drums added after the fact. Hansen has described looking at the timestamps of early recordings and finding himself working at 2 AM, 4 AM, 5:30 AM — building pieces in marathon sessions that would have been impossible without the energy that live collaboration produces.

The result was the first album Hansen has called a “true Tycho record.” Awake debuted at number 23 on the Billboard 200 and number 2 on Billboard’s Top Dance/Electronic Albums chart — commercial figures that validated the band-oriented direction. Critics who praised the record specifically praised the rhythm section. The Resident Advisor review, which was otherwise critical of the album’s songwriting, acknowledged that the rhythm section showed “nuance that Hansen lacks,” and singled out “Dye” and “Spectre” for their “wonderful percussive interplay.” Even the critics who were not entirely convinced found O’Connor’s contribution the most defensible element of the record.

What Awake represented, in retrospect, was the answer to a question Hansen had been asking himself since the first Tycho show: what does this music sound like when it is fully alive? O’Connor provided the answer.

The Drumming Style: Restraint as Mastery, Pocket as Philosophy

To appreciate what Rory O’Connor does behind a drum kit, it helps to think about what he does not do.

He does not fill. He does not showboat. He does not treat the spaces between the main beats as opportunities to demonstrate technical facility. His playing is defined by a quality that experienced drummers recognize as the hardest thing to learn and the easiest to describe: he knows when to stay out of the way.

This is what is meant by “pocket playing” — a phrase from jazz that describes the condition of a rhythm section so locked and so internally consistent that the space it creates feels solid rather than empty, that the notes not played carry as much weight as the notes that are. O’Connor plays in the pocket in the sense that his rhythmic contribution defines a space, and everything else in Tycho’s music inhabits that space with confidence because he has made it habitable.

The jazz influence in his playing is not about swing or improvisation in the conventional sense. Tycho’s music operates on a grid, within a strict timecode framework that synchronizes the band with the visual and lighting system. There is no stretching the beat, no rubato, no free time. But jazz drumming has given O’Connor something that transcends any specific stylistic vocabulary: an understanding of groove as a relationship between what is implied and what is stated, of dynamics as a communicative tool rather than a volume control, of restraint as an active choice that amplifies everything around it rather than a passive absence of activity.

His snare hits land with a particular authority that comes from the combination of technique and equipment. He is not crashing into the backbeat; he is placing it. There is a difference between a drummer who hits things hard and a drummer who hits things decisively, and O’Connor is the latter. When his snare lands on the two and four, it anchors the entire ensemble — the synthesizers, the guitar, the bass — to a single point of rhythmic certainty.

The kick drum in Tycho’s live show carries its own specific character: tight, dry, forward in the mix, landing with an electronic precision that would be at home in a programmed beat sequence. This is entirely intentional and required enormous engineering to achieve. The relationship between how the kick sounds acoustically and how it needs to sound in the context of Tycho’s mix is the central design problem of O’Connor’s kit, and the solution involves both the physical properties of the instruments themselves and the electronic augmentation of the triggering system.

O’Connor’s cymbal work is a study in restraint. He uses vintage Zildjian Avedis cymbals — instruments whose age and wear have softened their initial brightness, producing a slightly muted, papery quality rather than the cutting wash of new metal. Newer cymbals would compete with the synthesizers in the same frequency range; these older ones sit alongside them. His hi-hat patterns are typically sparse and purposeful — he is not maintaining a constant rhythmic texture but punctuating a rhythmic structure that has already been established.

The Big Fat Snare Drum dampening accessories on his kit are another piece of the same puzzle. They suppress the natural bloom and sustain of the drum, tightening the sound toward the dry, focused attack of an electronic sample. The kit sounds, in isolation, somewhat muffled and strange. In context — embedded in Tycho’s sonic architecture, sitting between Hansen’s synthesizers and Brown’s guitar — it sits exactly where electronic drums would sit, with the critical difference that a human being is producing it in real time.

This combination of technical choices — acrylic shells, vintage cymbals, heavy dampening, dry tuning — is not about making the kit sound bad. It is about making it sound appropriate. O’Connor has designed his instrument for a specific context, and within that context it is ideal.

The Hybrid System: Engineering the Space Between Acoustic and Electronic

The acoustic kit is only half of what O’Connor plays. The other half is invisible to most audiences and constitutes one of the more sophisticated live instrument systems in contemporary touring music.

Triggers mounted on the kick drum and snare drum send signals, every time O’Connor strikes either instrument, into a computer running REAPER — the digital audio workstation that forms the nerve center of Tycho’s live rig. Within REAPER, those trigger signals fire high-fidelity electronic drum samples that layer on top of the acoustic sound the audience hears from the physical kit. The effect is additive: the acoustic drum provides the human element, the warmth, the micro-variability of a person physically striking an instrument; the electronic sample provides the precise transient attack character of the programmed beats that defined the recorded material. Together, they produce something that sounds like both and is fully either.

The live drum microphones are also routed into REAPER, enabling real-time processing that goes beyond simple amplification. Sidechaining — the technique of using one audio signal to dynamically reduce the volume of another, commonly heard as the “pumping” quality in electronic dance music — responds to O’Connor’s playing in real time. Effects automation can change the processing characteristics of his drums dynamically throughout a performance. The live show is not a playback of the studio recording; it breathes and responds to what the musicians do.

The choice of REAPER over Ableton Live for the audio engine — Ableton being the default choice for virtually every other live electronic act in the world — is deliberate and has direct implications for O’Connor’s setup. REAPER offers superior stability under heavy plugin loads, which matters in a live context where a crash has no remedy. It allows for custom interface mapping that the Tycho technical team has built up over years of refinement. Most importantly, REAPER’s project tab architecture means that each song in the setlist lives on its own tab, with all synthesizer presets, guitar patches, and sample libraries recalled instantly when the band moves to the next track. This eliminates loading times between songs — a potential source of failure — and allows O’Connor’s trigger system to operate within a precisely configured context for every piece the band plays.

A second computer runs Ableton Live, but for a completely separate purpose: visual and lighting automation. Ableton is the master clock for the entire stage show — the synthesized drum patterns, the visual projections, the lighting cues all run off it. O’Connor, in his in-ear monitors, receives a SMPTE timecode from this system. He plays to that timecode every night, ensuring that his live drumming locks to the visual show with the precision that Tycho’s production design requires.

The central engineering challenge in all of this is latency. Electronic signal processing takes time — the trigger fires, the signal travels through the computer, the sample is retrieved and played back, and the result reaches the speakers. In most contexts, this delay is inaudible: a few milliseconds of audio latency is imperceptible in casual listening. In live drumming, it is catastrophic. Even a ten-millisecond offset between the physical strike and the electronic sample creates a flam — a doubling effect — that undermines the entire illusion. Managing latency requires careful configuration of buffer sizes, sample rates, signal routing, and the specific interface hardware connecting the acoustic kit to the computer. It is a constant engineering priority, and it is, O’Connor has acknowledged, the difference between a live show that works and one that doesn’t.

The Human Element: Playing Human Inside a Machine

None of the technical sophistication of O’Connor’s setup would matter if he played like a drum machine. The entire premise of having a live drummer in Tycho — the thing that justified Hansen’s decision to move from solo laptop performance to a live band — is that a human drummer does things that no sequencer can replicate.

O’Connor plays to a click track. Every note in his in-ear monitors is organized around a reference pulse that never wavers, that never rushes toward the chorus or relaxes on the bridge. He cannot depart significantly from that pulse without pulling the entire visual and lighting system out of sync. The click is, in this sense, an absolute constraint.

But a click track is not the same as a drum machine, and a drummer playing to a click is not the same as a sequencer playing to a tempo. The difference is in what O’Connor calls the “push-and-pull” — the natural micro-deviations from strict metronomic time that characterize all human rhythm. He might lay a snare hit two milliseconds early in a climactic passage, creating a sense of forward urgency, then settle two milliseconds behind on the resolution. He might dig into a ghost note in a verse groove that the programmed version approximated but never quite captured. He might bring a fill to a section that, in the studio recording, exists only as a chopped loop — finding the human gesture that explains the mechanical artifact.

These micro-deviations are not errors to be corrected. They are, in O’Connor’s understanding of his role, the entire point. A perfectly metronomic performance — every note precisely on the grid, every hit exactly where the sequencer would have placed it — would be, paradoxically, less accurate to what Tycho’s music is trying to be. The goal is not to replicate a drum machine. The goal is to do what a drum machine cannot: make the music feel like it is happening right now, created in this moment, by this person, in response to this particular crowd in this particular room on this particular night.

This balance — precise enough to hold the technical system together, alive enough to give the music its emotional pulse — is the specific skill that makes O’Connor irreplaceable in the Tycho configuration. Finding a drummer who can execute the technical requirements is difficult. Finding one who can execute them while remaining genuinely musical is rarer. Finding one who was already a fan of the music, who has internalized its aesthetic at the level of genuine love rather than professional competence, and who has spent a career developing the precise hybrid skills the project requires — that is the thing that happened in Hansen’s basement, and that has not needed to happen again since.

Key Tracks: Where O’Connor’s Contribution Is Most Audible

Certain tracks across the Tycho catalog function as demonstrations of what O’Connor specifically brings to the project. These are not necessarily the most famous songs, though some of them are. They are the pieces where his specific approach to rhythm is most fully expressed, where the things he does that no other drummer would do are most clearly audible.

“Dye” (Awake, 2014) is perhaps the clearest example from the first album cycle. The Resident Advisor review specifically praised its “wonderful percussive interplay” — a notable acknowledgment given the review’s overall skepticism toward the record. The kick and snare pattern in “Dye” does not simply maintain a groove; it has a melodic quality, a sense of the drum part conversing with the bass rather than simply supporting it. The interlocking of O’Connor’s kit with Brown’s bass playing produces something more than rhythm — it produces texture.

“Source” (Epoch, 2016) is where the interplay between the sampled foundation and the live top layer is most audible. Hansen’s compositional method on Epoch involved building songs from the loop library — fragments of O’Connor’s playing, processed and rearranged — and then having O’Connor play a live layer over the assembled structure. “Source” has a propulsive quality that feels both mechanically precise and organically unpredictable, because it is both: the programmed foundation provides the grid, O’Connor’s live performance provides the energy.

“Division” (Epoch, 2016) presents O’Connor’s most technically demanding recorded performance. The track operates in 7/8 time — seven beats per measure rather than the standard four or eight — and the asymmetry of the meter creates a perpetual sense of forward lean, a groove that never quite resolves into conventional pulse. Playing septuple meter feels inherently unstable; maintaining a tight, confident performance within it while locked to a visual show’s timecode is a specific technical achievement.

“Easy” (Weather, 2019) is where the loop library methodology is most legible. The shuffling breakbeat that opens the album is O’Connor’s drumming, played into a studio before the song existed, processed and shaped into the rhythmic bed on which everything else was built. The groove has a natural looseness that programmed beats cannot simulate — small asymmetries in the hi-hat pattern, a snare that sits slightly differently on each repetition — because it was captured from a drummer playing freely, without a song to play to.

“Devices” (Infinite Health, 2024) is the one track on the most recent album where O’Connor’s live drums are credited as the primary percussion. At five minutes, it is the album’s longest piece and one of its most cinematic, originally composed for film. His playing here gives the track a physical immediacy that distinguishes it from the programmed rhythms elsewhere on the record — a reminder of what is possible when the full acoustic-electronic hybrid system is deployed rather than the loop library approach.

The Recording Process: How Drums Are Made for Tycho Albums

O’Connor’s recording process for Tycho albums is not uniform across the catalog. It has evolved significantly from album to album, and tracing that evolution reveals both how Hansen’s compositional approach changed and how his trust in O’Connor developed.

On Awake, the process was relatively conventional by the standards of live band recording. Hansen and Brown had built structural frameworks and melodic sketches in the Lake Tahoe cabin sessions. O’Connor was brought in for the Santa Cruz phase to play live drums over those frameworks. Live drum tracking took place at Decibelle Recording Studios in San Francisco and at STS-9 Studio, with Count (Mikael Eldridge) serving as mixing engineer and an additional engineer named Ricardo Ayala also contributing. O’Connor played in a proper tracking room, with microphones capturing the full acoustic picture of the kit — room mics for space, close mics for punch, overhead mics for cymbal detail. The recordings were then subjected to Hansen’s layering process: the live drums became one element in a composite drum sound that also included programmed elements and processed material.

By Epoch, the process had inverted. Hansen’s stated goal was to return to his identity as a bedroom producer — to work alone, in his home studio in Berkeley, following ideas freely the way he had in the early Tycho years. The challenge was that working alone meant working without a live drummer. His solution was the loop library.

The Epoch drum sessions took place at Decibel Studios with engineer Robert Cheek. O’Connor entered the studio without demos, without chord progressions, without any melodic reference. His brief was to cover as much rhythmic ground as possible: different time signatures, different tempos, different feels, different textures. He played to old Tycho tracks, to tracks by other artists, to click tracks at various tempos. The goal was variety — to generate a vast palette from which Hansen could later select.

Hansen processed these recordings into a custom loop library: phrases of four, eight, and sixteen bars each, organized and catalogued. When he began writing Epoch, he worked from these loops as a sampler. He would find a phrase he liked, pitch it up or down to match a tempo he wanted, chop it into a new arrangement, build a song around it. The process was, as he described it, his sampling roots reconnected with the human quality of a live drummer — the best of both worlds.

After the songs were written and arranged, O’Connor returned to the studio to play a “top layer” over the assembled structures — live drums responding to the sampled versions of his own playing. The result is a drum sound that is simultaneously himself twice: once as a sample being used as raw material, once as a live performer responding to what he did.

For Weather, the loop library methodology was repeated and refined. O’Connor recorded at the start of the album cycle at Decibel Studios with Robert Cheek again engineering. The sessions were more targeted this time — Hansen had been through the process once and had a clearer sense of what kinds of loops he would reach for. O’Connor’s recorded performances became the rhythmic foundation of the entire album, including the tracks featuring Saint Sinner’s vocals. Hannah Cottrell’s melodies and lyrics were built over rhythmic beds that O’Connor had laid down without knowing what music would eventually surround them. Zac Brown’s guitar parts were fitted around those patterns. Everything on Weather, including the vocal performances, sits on top of Rory O’Connor’s drumming.

The room sound on the Decibel Studios recordings has a specific quality that distinguishes it from the harder, more forward drum sound of the Awake sessions. The Decibel tracks have a slightly more compressed, focused character — the room is in the sound but not dominating it, the drums speak quickly and cleanly, and the processing chain tightens them further before they enter the arrangement. This is the sound that listeners associate with the Epoch and Weather era of Tycho — precise but warm, electronic-feeling but unmistakably organic.

The “Rory Library”: A Compositional Resource

The practice of recording O’Connor’s drums before any songs exist — which crystallized on Epoch and was refined on Weather — is unusual enough in contemporary music production that it deserves dedicated attention. Most albums with live drums follow the opposite sequence: songs are written, arrangements are built, and then a drummer records parts that fit the finished or near-finished material. The drummer is, in this model, a performer executing a vision. The Rory Library inverts this.

When O’Connor enters the studio for a Rory Library session, he is not interpreting anything. He is performing into a void, trusting that what he generates will eventually serve as the rhythmic foundation for music that does not yet exist. His job in that room is to produce rhythmic material that has internal interest and variety — grooves that develop and shift, patterns that have texture and momentum — without reference to any harmonic or melodic context. He is, in effect, performing compositions that haven’t been composed.

Hansen then works with the recordings the way any producer works with a sample library — listening, selecting, trimming, arranging. A four-bar phrase that has a particular energy gets pitched down and becomes the bed of a slow, meditative track. An eight-bar groove with a complex hi-hat pattern becomes the foundation of something more propulsive. Fragments are joined, loops are stacked, fills are extracted from their original context and placed at structural moments in songs that bear no relationship to where they were originally played. The library is a palette, and Hansen paints from it.

What makes the Rory Library different from a standard sample library — the kind commercial producers can license from any number of sources — is not just its source but its character. The loops were played by a specific person with a specific aesthetic and a specific relationship to the music they would eventually serve. When O’Connor plays in those sessions, he plays like someone who knows what Tycho needs even when he doesn’t know what specific song will need it. His restraint, his understanding of pocket, his knowledge of how Tycho’s music uses rhythm — these qualities are present in every loop he generates, and they are qualities that no commercial library can supply.

Hansen has described recognizing, through the process of making Epoch, that O’Connor’s rhythmic vocabulary was not interchangeable — that it was a compositional resource worth documenting before the music existed, rather than a performance resource to be added after. This recognition produced the Rory Library methodology. It represents, in a practical sense, the moment when O’Connor stopped being Tycho’s drummer and became Tycho’s rhythmic collaborator.

The Live Show: From Laptop Performance to Band Experience

The transformation of Tycho from a solo laptop act to a live band — from a projected experience to a physical one — is one of the more consequential developments in contemporary electronic music performance. And at the center of that transformation is the visual fact of O’Connor behind his kit.

When Hansen performed solo, audiences could see him operating equipment. They could see his hands moving on a keyboard, his fingers adjusting a knob. The music was coming from the equipment, and he was the equipment’s operator. This is not an unfamiliar experience in electronic music — many of the most respected artists in the form perform this way — but Hansen found it insufficient. The audience could not see the music being made. They were hearing sounds and watching a person stand near the things producing those sounds. The gap between the two — between what was audible and what was visible — created a sense of unreality, of watching a presentation rather than attending a performance.

O’Connor’s arrival eliminated that gap, or at least relocated it. His kit is in the middle of the stage, physically large, visually dominant in a way that synthesizers and laptops are not. When he plays, the motion is visible from the back of a large venue: the arms raising and falling, the cymbals shimmering in the stage light, the snare recoiling under the stick. The music is being made, publicly, by a human being, and the audience can see it happening. This is the fundamental thing.

Within Tycho’s stage aesthetic — the massive projection screens, the precisely designed lighting rig, the visual vocabulary that draws directly from Hansen’s graphic design work — O’Connor’s position is the most visibly physical node in an otherwise technological landscape. Hansen’s synthesizers produce sound through speakers; his guitar, while played by hand, is relatively quiet and amplified electronically; Brown’s instruments are similarly mediated. O’Connor’s drums are violent. A snare hit is a physical event that exists before amplification, before processing, before the audience hears it — it is already happening when the stick reaches the head. Watching O’Connor perform in the immersive visual context of a Tycho show grounds the experience in bodily reality.

He is also, in a technical sense, the anchor of the entire show. Every other element of the live system — the synthesizers, the guitar, the bass, the visuals, the lighting — is coordinated through the SMPTE timecode that his in-ear monitors receive. This is counterintuitive: the drummer is playing to the machine’s clock, and the machine’s behavior is designed to feel like it is following the drummer. The relationship is a loop: the timecode gives O’Connor his reference, his performance generates the acoustic event that the system supports, and the system’s support makes his performance possible. He is simultaneously constrained by the machine and the human around whom the machine is organized.

The touring band that developed around O’Connor — with Zac Brown on guitar and bass, Billy Kim on keyboards and additional bass, and Hansen conducting the electronic core — produces a live sound that is, as Hansen intended from the beginning, neither a band playing electronic music nor an electronic act with added instruments. It is a specific third thing: a hybrid, with all the character that word implies. The seams are visible if you look for them and invisible if you don’t.

Album by Album: O’Connor’s Evolving Contribution

Awake (2014): The Arrival

Awake is the record that established O’Connor’s place in the Tycho sound. He was brought in after the Lake Tahoe writing sessions and played from the compositional stage rather than being added afterward. The drums on Awake are forward, physical, and assertive — the furthest Tycho has ventured into live-band territory. Hansen has described the album as “as far into rock as I’ll go,” and O’Connor’s drumming is a significant reason for that characterization: snares that crack rather than click, kick patterns with a physicality that programmed beats approximate but never achieve, fills that comment on the music’s emotional content rather than just marking structural transitions.

Tracks like “Montana” and the title track use O’Connor’s playing as a structural element — the drum patterns are not supporting a melody; they are building a momentum that the melody inhabits. The live show developed during the Awake touring cycle confirmed what the record had suggested: Tycho was now, definitively, a band.

Epoch (2016): The Synthesis

Epoch is where O’Connor’s contribution became most unusual in the history of recorded music. His role as the source material for a loop library — recorded before songs existed, then used as the rhythmic foundation for an album that became the most critically and commercially successful in the project’s history up to that point — represents a genuinely novel approach to the relationship between live drumming and electronic production.

His expanded role on Epoch also extended to guitar and synthesizer parts. The album credits list him as playing both, in addition to drums — a recognition that his musicianship extends beyond the kit and that his instincts about sound could add value in other areas of the recording. He was, by his own acknowledgment, uncertain exactly where all his contributions appeared in the final mixes; the recordings were “quite dense” and the division between his overdubs and Hansen’s own playing was not always visible from the outside. This opacity is itself revealing: by Epoch, O’Connor’s participation in the creative process had become organic enough that its boundaries were unclear.

The Grammy nomination that followed — Epoch’s nomination for Best Dance/Electronic Album at the 59th Annual Grammy Awards in 2017 — was the project’s first. O’Connor’s reaction was characteristic: “I don’t think any of us anticipated it. We’re all floored.”

Weather (2019): The Foundation

The Weather process represents the fullest expression of what the Rory Library methodology can achieve. By recording O’Connor’s drums at the very beginning of the creative sequence — before any songs existed, before Saint Sinner had been introduced to the project, before a single chord had been placed under a single note — Hansen made O’Connor’s rhythmic vocabulary the foundation from which everything else grew.

The album’s character, which feels simultaneously more immediate and more spacious than the Epoch material, owes much to this reversal. The grooves have a looseness that programmed beats would not produce, because O’Connor played them freely rather than to a grid. At the same time, they have the internal consistency of a specific drummer’s vocabulary — patterns that share an aesthetic even across widely different tempos and time signatures, because they come from the same body and the same musical intelligence.

Weather earned Tycho a second Grammy nomination in the same category. The Chemical Brothers won, but the recognition confirmed what the first nomination had suggested: the methodology had produced something distinctive enough to be acknowledged at the highest level of industry recognition.

O’Connor’s contribution to the Weather Remixes album, released in December 2020, is also notable. Under the Nitemoves alias, he contributed a remix of the title track “Weather” — the only instance in the remixes collection of a Tycho member remixing a Tycho track. The remix reflects the Nitemoves sensibility: atmospheric, electronic, built from a different structural logic than the original, but drawing on his intimate knowledge of where the piece had come from.

Infinite Health (2024): The Reduced Presence, Unchanged Importance

Infinite Health marks a shift in how O’Connor’s drumming was incorporated. Hansen’s stated goal for the album was to return to bedroom electronic production — to compose from synthesizers and drum machines first, adding other elements afterward, in the way he had worked in the early Tycho years. The album is therefore the most programmed-beat-forward of the post-O’Connor era.

O’Connor appears as a live drummer on “Devices” — the album’s longest and most cinematic track, originally composed for film, and the one piece on the record that explicitly requires the physical quality of live drumming to achieve its effect. His presence on that single track is decisive: it sounds different from everything around it, with an immediacy and physicality that the processed breakbeats elsewhere do not achieve.

His contribution to the Infinite Health touring cycle was as central as ever. The live show drew on the full catalog — setlists typically running fifteen pieces across six albums — and O’Connor’s hybrid system provided the rhythmic foundation for every one of them. His kit remained unchanged in its essential configuration, its acoustic-electronic hybrid character as precisely calibrated as ever.

The reduction of live drums in the studio process did not indicate diminished trust or role; it indicated that the creative direction Hansen had established required a different methodology for this particular record. When he described wanting to return to his earliest production instincts, O’Connor’s drumming was not excluded from that impulse — it simply found its expression in the live performance rather than the studio recording.

Nitemoves: The Solo Project and Its Relationship to Tycho

Under the alias Nitemoves, O’Connor has maintained an independent compositional practice that runs parallel to his work with Tycho and is genuinely distinct from it. The debut Nitemoves album, Longlines, was released in May 2012 on the Moodgadget label. Its creation under unusual circumstances — composed in three-to-six-hour chunks in the back seats of tour vans while on the road with Tycho and Com Truise — says something about both O’Connor’s relationship to creative work and the specific demands of a touring musician’s life. The margins between shows are long. He fills them with composition.

Longlines is an electronic album that draws on a different set of influences than Tycho. O’Connor has cited Erik Satie — the French composer whose “furniture music” concept pioneered the idea of sound designed as environmental texture rather than focused listening — as an influence whose minimalism and atmosphere connect to his solo approach. Tom Jenkinson, performing as Squarepusher, represents the complexity pole: hyper-programmed breakbeats and jazz bass at impossibly high speeds, the outer boundary of what rhythm can be made to do by a musician who has internalized it fully. Billy Corgan provides the emotional dynamics model: dense, layered, capable of both delicacy and overwhelming force.

These three references — minimalism, rhythmic complexity, emotional dynamics — are the triangulation points of O’Connor’s solo aesthetic. They are also, more quietly, the triangulation points of his Tycho work. The restraint he shows behind the kit with Hansen is Satie’s restraint applied to percussion. The precision with which he executes complex polyrhythmic patterns is Jenkinson’s complexity applied at a lower temperature. The emotional authority of his backbeat — the sense that the two and four matter, that the snare is not just timekeeping but statement — comes from the Corgan influence filtered through years of playing music that aspires to emotional resonance without words.

In 2023, O’Connor began collaborating with visual artist and VJ Lisa Mizuno Misola for interactive audiovisual performances under the Nitemoves banner, introducing a visual dimension to the solo project. The connection to Tycho’s own synthesis of visual and sonic identity is obvious: O’Connor has spent over a decade in a project where the visual design is as considered as the music, and this has influenced how he thinks about what his own creative work should look like.

Scott Hansen has been a consistent public champion of Nitemoves. He has posted about the project on the ISO50 blog, premiered tracks, and described O’Connor as a genuine creative peer rather than merely an employee. The Nitemoves releases feature Hansen’s visual art — maintaining the aesthetic thread between the two projects in a way that, as with the com Truise connection that led to O’Connor joining Tycho in the first place, demonstrates that the most significant professional relationships in O’Connor’s career have been built on genuine mutual respect for each other’s artistic work.

O’Connor currently lives in Washington, D.C. — far from Westfield, from Brooklyn, from San Francisco, from the Sacramento music scene that produced so much of the Tycho story. Distance has not attenuated the work.

Drummer in an Electronic Project: The Unique Creative Space

The question of what it means to be a drummer in an electronic music project — what the role requires, what it enables, what it forecloses — is one that O’Connor is positioned to address with unusual authority. He has spent more than a decade navigating exactly this tension, and his navigation has been explicit and thoughtful rather than simply pragmatic.

Electronic music, in its essence, is music that achieves through machines what acoustic music achieves through human performance. The drum machine does not tire. It does not rush. It does not miss a beat because its mind wandered. This is precisely what makes it useful and precisely what makes it, in certain contexts, unsatisfying. Music that never departs from its own intentions, that never responds to the energy of a room or the accumulated fatigue of a long performance, produces a different emotional effect than music that does. Whether that difference matters depends entirely on what the music is trying to do.

What Tycho is trying to do — to create music that feels simultaneously crafted and immediate, both perfect and alive — requires the tension between electronic precision and human variability. O’Connor is the embodiment of that tension. His job is to be precise enough that the machines can work alongside him and loose enough that the humans in the audience can feel him.

He has spoken about the “powerful ambiguity” of wordless music — the way that instrumental composition creates emotional resonance without literal content, allowing listeners to bring their own experience to the sound. This quality is what Tycho has always pursued, and it is what O’Connor serves. His drumming does not tell you what to feel. It creates conditions in which feeling becomes possible. The restraint, the pocket, the micro-deviations that humanize the grid — these are not expressive statements so much as expressive invitations.

The specific challenge of being a drummer who is also a compositional resource — whose recorded performances become raw material before they become finished music — requires a kind of creative double-consciousness that few musicians have been asked to develop. When O’Connor plays the Rory Library sessions, he is performing for an imagined future context, generating material whose purpose he cannot know. He has to trust that his instincts about what constitutes good rhythmic material will prove applicable to situations he cannot foresee. This is, in a sense, the drummer’s equivalent of writing songs without knowing what key they’ll eventually be performed in: a fundamental uncertainty about context that can only be answered by having enough of a voice that whatever you do will make sense.

The Touring Relationship: Years on the Road with Hansen and Brown

O’Connor has been on the road with Tycho continuously since 2012. The Dive tour, the Awake tour, the Epoch cycle, the Weather World Tour, the Infinite Health tour — each touring cycle has brought new venues, new configurations, new challenges to the live system, and the accumulated weight of years spent in the particular intimacy of band life on the road.

The Tycho touring crew operates with a deliberately familial dynamic. Hansen has consistently sought musicians who share pre-existing rapport and a common aesthetic sensibility, prioritizing chemistry and personal compatibility alongside technical skill. O’Connor’s initial connection to the project through the Ghostly International community — coming in as someone who already had relationships with the label’s artists and who had demonstrated his capabilities in a comparable live context — meant that the familial dynamic was partly pre-existing rather than constructed.

The Zac Brown relationship is central to understanding how the live band functions. Brown, who has been with Tycho since 2010, is the member most responsible for structural clarity — what Hansen describes as a “pop sensibility” that pushes arrangements toward concise, emotionally direct forms. His guitar and bass work provides the harmonic and melodic anchor around which O’Connor’s rhythmic contributions operate. In live performance, the locking of Brown’s bass against O’Connor’s kick drum is the engine of Tycho’s forward momentum: two musicians who have played together across hundreds of shows, who understand each other’s tendencies and trust each other’s instincts, producing a rhythmic foundation that the rest of the music can sit on with confidence.

Billy Kim’s addition to the live band in 2016 — handling keyboards, additional bass, and synthesizer duties — expanded the band’s capacity to cover the layered studio arrangements without increasing the demands on any individual member. For O’Connor, Kim’s presence meant that the textures he was responsible for establishing rhythmically were supported by a richer harmonic and melodic environment than the three-piece configuration had allowed.

The Tycho live band in 2024 is as stable as any in contemporary electronic music. Hansen, Brown, O’Connor, and Kim have now toured together for eight years. The trust built over that time is audible in the tightness of the live performances — the sense that each musician knows exactly where the others are, rhythmically and emotionally, at every moment in every piece.

The Drum Community: How Drummers Hear O’Connor’s Work

Within the drumming community — the subset of musicians who pay particular attention to what happens behind the kit and have opinions about it — O’Connor’s work with Tycho has generated a specific and appreciative response that is distinct from the general audience’s experience of the music.

For drummers, the technical challenges of O’Connor’s position are legible in a way they are not for most listeners. The management of a trigger system while maintaining live performance quality, the latency management required to keep acoustic and electronic elements in sync, the specific discipline of playing to a timecode while remaining musically alive — these are challenges that drummers understand from the inside, and the fact that O’Connor executes them night after night at the level that Tycho’s music requires is a source of genuine respect.

His drum choices are discussed in online forums and podcast interviews oriented toward players. The Big Fat Snare Drum company — the manufacturer of the dampening accessories O’Connor uses on his snare — has featured him in their artist profile content, where he discussed his top five influential records and spoke about his approach to the instrument. The Drum Click, a podcast focused on drumming and drummers, included O’Connor in a 2022 feature that provided one of the more detailed public accounts of his influences and approach available.

The specific qualities drummers note in his playing — the pocket, the restraint, the dry precision that suggests electronic beats while remaining unmistakably human — are the same qualities that make him effective in the Tycho context, but they are appreciated differently by players who have tried to develop these skills themselves and know how difficult they are. Playing with restraint is harder than playing with activity. Knowing what not to play is a more advanced skill than knowing what to play. O’Connor has developed both.

His work on tracks with unusual metric structures — “Division” in 7/8, the rhythmic displacement of “Slack” and “Rings” — has drawn particular attention from drummers interested in odd-time performance. Executing asymmetric meters within a tight electronic framework, without the visual and kinetic cues that typically help drummers maintain complex time signatures, represents a technical achievement that the broader audience experiences as a vague sense of the music not quite sitting where they expected, and that drummers recognize as deliberate and precise.

The Nitemoves project has a separate following within the drum community — listeners who came to it through interest in O’Connor the drummer and found a composer whose work rewards attention as music rather than as a vehicle for impressive percussion. The two bodies of work have helped establish him as something more than a hired player: a musician with a compositional voice, aesthetic convictions, and the technical versatility to express them in multiple contexts.

The Philosophy: Ambiguity, Economics, and the Honest Calculus of a Musical Life

O’Connor has been more candid in public discussions of his career than most musicians of his level of visibility, and the candor reveals something about both his character and his understanding of what it means to organize a life around making music.

The first recurring theme is a genuine fascination with what he calls the “powerful ambiguity” of wordless music. This is not a marketing phrase. It is a description of something specific: the way that music without lyrics creates emotional resonance without fixing the nature of that resonance, allows listeners to bring their own experience to the sound and find it reflected there. Tycho is the project that made O’Connor a fan before it made him an employee, and the quality of the music that drew him in as a listener — its refusal to define, its preference for implication over statement — is the same quality that animates his work as its drummer.

When O’Connor plays a passage of Tycho music on stage, he is not illustrating a story or supporting a narrative. He is participating in the creation of a condition: a sonic environment in which feeling becomes possible without being prescribed. His restraint in those passages is a form of respect for the listener’s right to bring their own experience. His precision is a form of commitment to making that condition as clear and consistent as possible. The philosophy and the technique are connected.

The second recurring theme is economic honesty. O’Connor has stated plainly that “supporting oneself fully through music is not easy” — a statement that lands differently coming from the drummer of a Grammy-nominated act than it might from a musician struggling for visibility. It is a remark that acknowledges what most musicians in the independent world know and few say directly: that the collapse of traditional music revenue streams has made the calculus of a musical career genuinely difficult, and that choosing to pursue it anyway involves real sacrifice.

His career philosophy, as he has articulated it, prioritizes personal fulfillment and art creation over financial security. The paper route for the four-track recorder, the Brooklyn years building professional relationships in a scene without institutional support, the Nitemoves albums composed in tour van back seats — these are all expressions of the same orientation: music matters enough to organize a life around it, even when that organization involves accepting conditions most people would find uncomfortable.

This honesty is part of what makes O’Connor a distinctive voice in the community around Tycho. He is not performing effortless passion or projecting financial stability he may not feel. He is describing, with precision and without self-pity, what it actually costs to do the thing he has chosen to do — and implicitly making the argument that it is worth it.

Legacy: The Parts Were Written Around Who He Is

The conventional description of an irreplaceable musician typically invokes technical skill: no one else can execute these parts. This is usually either false or trivially true. Most parts can be learned by a sufficiently skilled musician given sufficient time. What actually makes a musician irreplaceable is something different.

Rory O’Connor is irreplaceable in Tycho not because his parts cannot be learned, but because his parts were written around him. The loop library methodology made this literal: albums were built from recordings of O’Connor’s specific rhythmic vocabulary before the songs themselves existed. The grooves in Epoch and Weather carry O’Connor’s particular timing, his specific relationship to the pocket, his characteristic way of approaching a fill or a transition. Another drummer, executing the same parts with the same equipment, would produce something technically similar and aesthetically different, because the parts originated in a specific person’s way of playing and carry that origin in their character.

Hansen recognized this, and the recognition produced the methodology. The Rory Library is the institutionalization of a fact: that O’Connor’s rhythmic voice is not interchangeable with another drummer’s rhythmic voice, and that it is therefore a compositional resource worth documenting before the music exists. This acknowledgment — of a collaborator’s irreducible individuality as a creative force — is the highest form of artistic trust.

O’Connor has been a core member of Tycho across the project’s peak creative and commercial years: the Awake period that broke the band into a broader consciousness, the Epoch period that represented the instrumental vision fully realized, the Weather period that extended the sonic vocabulary into new territory, and the Infinite Health period that returned to foundational concerns with increased confidence. Two Grammy nominations. Festival stages across four continents. A place in the history of how electronic music can be performed live, as something more than a DJ set and more than a rock concert, as a genuinely hybrid form with its own aesthetic identity and its own demands on the musicians who attempt it.

The story begins in Westfield, Massachusetts, with a boy who got a paper route to buy a four-track recorder. It continues in Brooklyn, in the Ghostly International community, on the Com Truise tour. It reaches its defining moment in a San Francisco basement, where two musicians who had never played together discovered they were working in the same language. And it continues, through hundreds of shows and four more albums and a custom sample library that an artist built from the recordings of another artist’s specific, irreplaceable way of playing.

The music became what it became because of how Rory O’Connor hears rhythm. That is the whole story, and it is enough.
