I've never been one that thinks that the function of an instrument is to approach the purity of voice or the structure of a beautifully sung line.

I didn't get where I am today by being timid, young man.

To speak about notation as the only way that you can guarantee structure of course is already very suspect.

There's an institution here called the National Sound Archive, and there's a character who works there, Paul Wilson. He takes a very special interest in the history of the music and advised Martin Davidson of the existence of these tapes.

We all listened to a lot of recorded music, especially American jazz, modern jazz, and that's where our studies were and our inspiration came from.

So what starts is ad hoc and you never know where it's going to lead, so it's important to keep an open mind about those things.

So in the sense that we were all dealing with that freer approach, yes, it was certainly one of the first contacts, perhaps the first contact, when Peter came that summer. So it's a very pivotal moment that is documented there.
