Selection Sixteen is a 1999 album by Squarepusher, released on Warp Records. According to the CD, the cover-art is from a film called Acid Trayners 4, which seems to be different pictures of an oscilloscope. Throughout the record the bass, hooked to an audio/midi converter, played an important part in the composition of synth and drum parts.
Most releases of Selection Sixteen include "Anti-Greylord Protection Scheme Prelude", which was originally released as a separate EP with a slightly different track order. "Ceephax Mix" was created by Squarepusher's brother, Andy Jenkinson, aka Ceephax Acid Crew.
On the original release, "Schizm Track #2 Mix" is the first track.
