Cylob is the alias of electronic music maker Chris Jeffs. Between the years of 1993 and 2004 he released 13 singles and 5 albums on Rephlex, in addition to the EP "Spider Report" for Breakin' Records. His remix credits include reworkings for Mogwai, Aphex Twin, Soulwax (2 many DJs), Cristian Vogel and Mike Flowers Pops. Although Cylob's music is predominantly instrumental, ranging from ambient styles to aggressive dancefloor sonics via pop pastiche and electronic funk, his most well known tracks have been the underground hits "Rewind" and "Cut The Midrange, Drop The Bass" which pioneered computer-generated rapping and singing on top of signature Cylob beats.


Cylob Industries was set up in 2007 to release the music of Cylob. So far, six albums and three singles of new music have been released, including under the alter-egos nonprivate and Ambient News.

The end of 2014 sees the Cylob back catalogue being given an official digital release for the first time. "Cylob Music System 3000" is a compilation of the two "Cylob Music System" EPs which first appeared on Rephlex in 2004, along with the four tracks released on the vinyl version of the "Spider Report" EP on Breakin'. The tracks were created using the first version of Cylob's self-made sequencing application, hence the name. Styles range from the heavy duty electronic funk of "Spider Report" and "Total Information Awareness", the twisted, detuned melodies of "Inseminoid" and "Chuckle Midget", bells and beats on "We Never Said Goodbye", and the heavy-duty 303 action on the appropriately named "Acid Inseminoid".
