To me, I took a militant attitude towards sounds. I wanted sounds to be a metaphor, that they could be as free as a human being might be free. That was my idea about sound. It still is, that they should breathe … not to be used for the vested interest of an idea. I feel that music should have no vested interests, that you shouldn't know how it's made, that you shouldn't know if there's a system, that you shouldn't know anything about it … except that it's some kind of life force that to some degree really changes your life … if you're into it.

Quoted in a 1976 interview, published in Desert Plants by Walter Zimmermann.
