Evan Parker — British Musician born on April 05, 1944,

Evan Shaw Parker is a British free-improvising saxophone player from the European free jazz scene... (wikipedia)

Improvisation is a compositional method.
So I'm looking to the saxophone as a resource which has its own unique set of possibilities. I'm looking to exploit them and develop them and have the fullest range of possibilities of the saxophone be known.
Certain kinds of speed, flow, intensity, density of attacks, density of interaction... Music that concentrates on those qualities is, I think, easier achieved by free improvisation between people sharing a common attitude, a common language.
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.
Those early steps are very important in understanding the evolution. But in themselves, maybe now you need the later records to understand the significance of the earlier records!
