• Frontman Wayne Coyne explained this hypnotic, bass-led groove in the album's press notes: "A simple, menacing groove, but also a kind of grinding machine. It implies a primitive self-exploration. To understand life, we must, sadly, understand death. To know the value of love, we must try to understand the nature of evil. To know ecstasy, one must explore suffering. Crazy, panic drums by Kliph.(Scurlock)."
• While planning the double album, the band thought they'd record around 10 semi-normal songs and 10 more "freakout" tracks - experimental, open-ended jams that would allow them to explore weirder, more self-indulgent ideas. "The more we played around with it, the less we became inclined to do the other part of the record," Wayne told Diffuser. "Your Bats' and 'See the Leaves,' those were supposed to be the things we were doing on the side. And then the side became the thing. I think if we didn't do those things, we wouldn't be happy. That was probably the first time where we scrapped what we'd planned to do and went with what we're starting to do. And that's pretty radical."
