This is a fantastic book, I've just read the first 4 'chapters' and I'm captivated. He's brilliant but in the interviews/lectures in the book he comes off as very amiable and his philosophy on music is very approachable and almost epiphanic. I reccommend this book for anyone even slightly interested in musical philosophy. It's out of print, though you can find it online without too much trouble. You could also check your local library (which is where I got it from). Libraries are shamefully under-utilized resources.
