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.
The cover shows several buildings from downtown Toronto, including the Royal York Hotel and the Canada Trust Tower.
In January 2015, the label re-issued the album on vinyl format on a limited pressing of 1000 copies. The vinyl version was originally intended to feature the album by itself, but due to the length of the album, it would not be able to fit in a single LP and would be too little for 2LPs. Instead, the label tried to find outtakes coming from these sessions in order to fill the gap resulting from pressing the album on 2LPs, but Dickerson explained that there were no outtakes left from these sessions. Instead, the label decided to go ahead with the re-issue by filling the gap with 6 bonus songs, 3 from the album Cobra Strike and the other 3 from Funnel Weaver.
