Jazz, for me, is a closed circuit, like the term baroque in the world of classical music.

When we are on tour we also take chances.

I feel very strongly when there's no chance for me to find a key to a piece.

The only element of jazz that I keep is improvisation.

Other times I say: I would very much like to try to do something with this music, but after playing for a few minutes, I have to break off.

There's a certain phraseology involved in jazz, and I've moved away from that.

Coltrane was moving out of jazz into something else. And certainly Miles Davis was doing the same thing.
