“In order to do something that seems new, you have to strip away everything that's traditional, take away all the things that give it its formula or its identity. You have to get everything that's normal and break it. And even then you still are at the mercy of having grown up thinking of music a particular way, and that's where the cut-up process came in, because you could then break your own perceptions and actually end up with new comprehensions that you would otherwise not have.”
