Tetrad is the dubstep and bass music project of L.A.-based musician, producer, songwriter, and DJ Cheyne Bush. A lifelong musician, Cheyne learned jazz on saxophone and guitar in school, and punk and experimental music at home. 

Gaining experience as a youth, starting a band called Issue 89, playing a fusion of street punk and ska, and joining a metalcore band MidMourn on vocals and synthesizers, he turned to electronic music when he started experimenting with music software and DAWs such as Ableton Live and discovered artists such as Aphex Twin, Boards of Canada, and Autechre. As he was developing his style and listening to deep minimal techno and IDM, a new influence came out of his interest in 4x4 and 2-step Garage music -– this new influence was dubstep, in the form of Burial and Shackleton. Discovering the Hyperdub and Skull Disco artists, as well as the early DMZ, Deep Medi, and Chestplate releases, instilled a shift towards this new musical direction.

Following multiple collaborations with artists such as Brukha as Friendly Strangers in 2007 and LMNOP as Cybertooth in 2009, Cheyne started recording solo as Tetrad in 2015 and has since released a clutch of deep and weighty dubstep tunes on labels like American dubstep imprint Sure State and Heavyweight in the UK. Most recently, he’s released his vinyl debut with the 7” single “Awaken Dub” on Portland’s vaunted ZamZam Sounds label, and a follow-up 7" with newly debuting Bay Area label Material Sound with his tune "Eazy Street." Following this was his first release on a 12" record, which includes a collaboration with his brother, Dillon Bush, under his moniker Ahkur, to be coming from Bristol's dark dubstep haven Foundation Audio. Most recently, Cheyne & Dillon return with a release on notorious US dubstep label Silent Motion and now Cheyne anticipates the release of his remix of a tune by ZamZam Sounds co-honcho E3 through Joe Nice's highly valued label Gourmetbeats, to be released on 12" vinyl in August.
