David Tudor, pianist known mainly for his association with John Cage and Merce Cunningham, gives good interview.
You have to understand that. I mean, there were many common interests that brought me and John Cage together, and that causes us to continue working with enthusiasm together. The thing was that I could do anything that he asked, there was no proposition that I couldn't attack in my own way to bring about a solution...You see, I hear sound off the page, so it was very exciting for me, even without sitting down and trying to do it.
