Originally released in 1993, Surfing on Sine Waves is the second album released under the Warp Artificial Intelligence series (the series also includes the two titular compilations, as well as contributions by Autechre, The Black Dog, F.U.S.E. and more).

Surfing on Sine Waves is also the sole album released under Richard D. James’ (aka Aphex Twin's) Polygon Window alias. The name “Polygon Window” originally appeared as a track name under Richard D. James’ other pseudonym The Dice Man, as the track title for his submission on Artificial Intelligence.

Surfing on Sine Waves was chosen as a title by Rob Mitchell based on a quote by Richard D. James. The album debuted at #2 on the UK dance charts.

The new expanded track list combines the original record and its four-song companion EP, Quoth, which came out the same year.

Fast forward 32 years to 2025, Surfing on Sine Waves (Expanded Edition) sees the pair of companion releases as a single entity.
