Jenkinson became interested in music at 12 years old when he would go into his brother's room and play his brother's SH-101.[4] He started a rock band called "C-Fax",[when?] and kept the name for his later performances.[5]
Ceephax's music from 1997 to 2002 and beyond used mainly vintage (especially Roland) drum machines and synthesizers such as the TB-303. This music was often recorded onto a cassette tape deck. The music was released on vinyl records and cassette tape on underground record labels, such as Breakin' Records, Lo Recordings, and Firstcask. This primitive acid house aesthetic and methodology countered the growing popularity of the computer music and compact disc releases of the time. Rephlex Records and Warp Records also released Jenkinson's remixes of Squarepusher around this time.
From 2003 onwards, as well as his more typical acid style, he has also released drum and bass songs made on old samplers, an Amiga, and various early digital synthesizers. His set on Mary Anne Hobbs' show Breezeblock in 2003, and more tracks such as "Castilian" and "Arcadian" also indicate an interest in Chiptune music.
From 2007 onwards, he has had full releases on the record labels Rephlex and Planet Mu. He also continues to release on Firstcask and other independent labels such as WéMè, Bugklinik, and his own label, Waltzer.
Ceephax's live shows are set apart from the popular laptop style of live electronic performance by exclusively using only analogue and early digital equipment and occasionally an Amiga computer. Frequently used hardware includes TB-303, TR-909, TR-707, SH-101, Kenton Pro-2000, and Yamaha RS7000.[6] These sets range from old school house, acid house, techno, drum and bass, and gabber. He has also produced several music videos, predominantly using old video equipment and early computer animation.
