Kennedy first began releasing techno records while he was still a student, attending university in Manchester. Four EPs appeared in 1996, including two on ZET, an early label founded by Karl O'Connor (aka Regis). An album of paranoid, convulsive tracks titled Specific Formal Patterns was released by the label in 1997, and Kennedy began playing gigs around his home country as well as Eastern Europe, thanks to his frequent collaborator Umek. As he became increasingly more prolific, he released records under the pseudonyms Helki Törsnum, Reducer (on his Instillation label), and Tomito Satori (on Exhibit Records), as well as his own name. He also founded the Asymmetric label in 1999, through which he released some of his most challenging, experimental productions.
Kennedy's second full-length, The Bigger Picture, appeared on Missile Records in 2001. He continued releasing a steady stream of singles, mainly on Asymmetric, while maintaining a full-time job instead of trying to make a living strictly as a DJ/producer. In 2004, Asymmetric stopped pressing vinyl records, and all of his subsequent releases through his label were free downloads. Belgian DJ Kr!z founded the dark techno label Token in 2007, and Kennedy soon became one of its flagship artists, releasing hordes of well-received records for the label. September Pieces, an experimental full-length CD, was released by Swedish label Electronic Desert Recordings in 2010. Kennedy's first Token full-length, Vaudeville, appeared in 2014, and was easily his most cohesive album to date. Following several more singles for the label, Kennedy released the vast, expressive Strata in 2018.
After releasing another EP on Token, 2019's Trajectory, Kennedy and Samuli Kemppi collaborated for Catalogue of Errors, issued by Blacklabel Distillery. The acid-influenced Arcadian Falls was issued by Voltage in 2020. A handful of EPs appeared in 2021, including XX 4 (with Marco Lenzi) and Recovery Mode. ~ Paul Simpson, Rovi
