Guitarist Bill Kelliher explained to The Skinny magazine that with this song, "Troy [Sanders, bass/vocals] and I were down at the practice space waiting for everyone else to show up one day. He was playing a couple of the parts he had, then I stuck on my delay pedal and started playing along – we just started building from there. Brent came in and heard us play, we asked him for another part and he says 'OK, here you go' – came up with the next riff.
