Sleep D: Biography, Discography and More | EDM Encyclopedia
Introduction
Sleep D is an Australian electronic music duo from Melbourne, consisting of Maryos Syawish and Corey Kikos. Active since 2013, they have established themselves as consistent figures in the Australian underground electronic music scene. Their work centers around hardware-based production and live performance, favoring analog synthesizers, drum machines, and spontaneous composition over studio-based digital production.
The duo operates their own label, Butter Sessions, which they co-founded. The label serves as a primary outlet for their own material as well as releases from other Australian electronic producers. This independent infrastructure has allowed them to maintain creative control over their output from their first release in 2013 through their most recent album in 2023.
Melbourne’s electronic music environment has played a role in their development. The city’s warehouse party culture and community-focused approach to dance music provided the context for their early performances and recordings. Their DJ sets and live shows often emphasize long-form mixing and extended sets rather than quick transitions.
Genre and Style
Sleep D’s music falls primarily within acid house and electronic dance music. Their approach to acid house centers on the use of the Roland TB-303 bass synthesizer or its digital equivalents, which provides the squelching, resonant basslines that define the style. Rather than treating acid as a retro reference, they use these sounds as building blocks for tracks that range from straightforward dancefloor material to more abstract electronic compositions.
The acid house Sound
Their production style relies heavily on jamming with hardware. Tracks often develop from extended improvisation sessions that are then edited down to their final forms. This method gives their recordings a spontaneous quality, with slight timing variations and filter adjustments that digital sequencing typically eliminates. The result is music that maintains a human feel despite being primarily electronic.
Rhythm plays a central role in their compositions. Drum patterns draw from house music‘s four-on-the-floor foundation but frequently incorporate elements of electro, techno, and breakbeat. Tempos vary across their discography, allowing individual releases to serve different functions: some aimed at peak-time club play, others suited for home listening or warm-up sets. This variety prevents their catalog from settling into a single predictable template.

Discography Highlights
The Jackal (2013) marked their first release, establishing their presence in the Australian electronic music landscape. The record introduced their hardware-focused approach and set the template for their subsequent work.
The Jackal, Pt. 2 (2016) revisited the concepts of their debut EP three years later with expanded production techniques.
2017 proved productive for the duo. From 50, After The Rain, and Red Rock each arrived that year, demonstrating their ability to maintain quality across multiple releases within a short timeframe.
Rebel Force (2019) served as their debut album, collecting their evolving fl studio work into a full-length format. The album demonstrated their capacity for longer-form compositions alongside dancefloor-oriented tracks.
Flashed Glass (2021) followed two years later, refining their production approach with cleaner mixes and more varied textural elements.
Electronic Arts (2023) represents their most recent full-length, released on Butter Sessions. The album continues their exploration of acid-inflected electronics while incorporating new rhythmic patterns and sound design elements acquired over their decade of activity.
Famous Tracks
Sleep D’s catalog maps a decade of acid house production, beginning with The Jackal in 2013. This debut EP established their hardware-driven approach: 303-influenced sequences paired with propulsive drum programming and minimal arrangement. The 2016 follow-up, The Jackal, Pt. 2, expanded on this framework with tighter rhythmic structures, deeper low-end frequencies, and more developed melodic patterns.
A burst of productivity arrived in 2017 with three EPs. From 50 leaned into percussive, club-focused material with emphasis on rhythm over melody. After The Rain explored more atmospheric territory, introducing ambient textures into their acid house foundation. Red Rock bridged these two approaches, balancing dance floor momentum with detailed sound design. Together, the trio of releases demonstrated range within self-imposed limitations.
The transition to full-length albums began with Rebel Force (2019). This LP collected Sleep D’s evolved production sensibilities into a cohesive listening experience, demonstrating an ability to sustain ideas across longer formats. The album balances high-energy tracks with slower, more contemplative passages. Flashed Glass followed in 2021 with refined sound design, more complex rhythmic patterns, and an expanded tonal palette. Their most recent album, Electronic Arts (2023), continues this trajectory with tighter arrangements and broader synthesized textures, suggesting ongoing development in their production approach.
Live Performances
Sleep D operates within Australia’s underground electronic music circuit, performing at venues and events oriented toward hardware-based dance music. Their live sets center on analog synthesizers and drum machines, using these instruments to recreate and extend the textures found on their recordings in real time. This method prioritizes physical interaction with equipment over laptop-based performance, creating conditions where no two sets sound identical.
Notable Shows
The structure of their shows frequently departs from recorded versions. Material from their albums serves as starting points for extended improvisations, with filter cutoffs, resonance, and sequence patterns manipulated throughout each set. This approach aligns with acid house performance traditions where hardware becomes a vehicle for spontaneous composition rather than pre-programmed playback.
Their sets prioritize sustained energy and gradual tonal shifts over abrupt transitions. This method creates extended arcs suited to longer time slots, allowing tension to build across hours rather than minutes. The pacing reflects the influence of classic acid house DJ culture while incorporating live elements that distinguish Sleep D from standard club bookings.
Appearances across Australian venues have positioned the project within a network of artists and labels committed to hardware-driven electronic music. These performances connect local audiences to global acid house lineages while maintaining a distinct production identity tied directly to their studio output.
Why They Matter
Sleep D’s significance stems from consistent output and commitment to hardware-based acid house across a ten-year span. The progression from their first EP in 2013 to their third album in 2023 documents a producer refining a specific sonic vocabulary without chasing external trends.
Impact on acid house
Their discography provides a substantial body of work within a niche often dominated by singles and short-form releases. By committing to both EP and album formats, Sleep D has explored acid house as a vehicle for extended listening, not just functional dance floor material. The three full-lengths demonstrate an ability to structure longer releases that reward complete listens rather than isolated track selection.
Within Australian electronic music, Sleep D represents a strain of production rooted in analog synthesis and restrained arrangement. This approach connects local scenes to international acid house lineages without relying on retro pastiche, emphasizing continuity with the genre’s founding principles rather than nostalgia for a specific era or sound.
The consistency of their release schedule stands out in underground electronic music, where long gaps between output are common. Albums arriving in 2019, 2021, and 2023 suggest a disciplined studio practice focused on gradual development and regular output, building a catalog that rewards chronological exploration.
The shift from EP releases to album-length projects marks a significant development in their career. Early works function primarily as dance floor tools, while later albums incorporate broader dynamic range and more varied tempo choices. This evolution indicates growing confidence in their production abilities and a willingness to explore beyond established comfort zones.
