"The voices [in the music] are sometimes from old TV shows or tapes we've made. We have a lot of stuff we've collected, going back to the early '80s. But half of the time, it's things we've had friends record specially for us. We create tapes all the time. Practically everyone we know has been roped into recording something for us at some point. [...] We often get friends to sing things for us with the intention of building a melody around it."
