Population Override is the twelfth studio album by Buckethead, but it could be seen as his first full collaboration with keyboardist Travis Dickerson. The album is a tribute to the "great vinyl records of the '60s and '70s", with songs more often than not drifting off into long jams.
Almost all the music is just us communicating as we play. The songs started as a riff that either I or Bucket would start playing and then we would all go from there. On some of the tracks we worked out some cord [sic] changes but a lot of them were just made up as we went. We worked out a lot of stuff as overdubs and that helped give it structure. (...) We recorded the little guitar snippets just for what they were used for, track segues.
