"I think that music has to have danger, you have to be right on the precipice to really be interested, not gliding along playing something you know. If you never get on the brink you're never going to learn what excitement you can rise to. You can only rise to great heights by danger and no great man has ever been safe."
I read this just now in the book "Experimental Music: Cage and Beyond" while researching for an assignment, and it was exactly what I needed to read. Only slightly relevant to the assignment, but 100% relevant to my state of mind. Thanks Michael Nyman!
