Jenkinson is also known simply by the pseudonym Ceephax, which is a reference to the BBC teletext service Ceefax.

This primitive acid house aesthetic and methodology countered the growing popularity of the computer music and compact disc releases of the time.

From 2003 onwards, alongside 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.
