Seems I was coding away in my own little world most of the day to Aphex Twin's "Meltphace 6". Now, all I can remember of the day is that tune, which is presently stuck on infinite loop entirely in my head
Just having the same experience again, this time with Royksopp's two remixes of Steve Reich's "Electric Counterpoint Part III: Fast"
For those unfamiliar with the third part of Electric Counterpoint, it's where the guitar sample in The Orb's "Little Fluffy Clouds" came from.
