I love Bruce and his music, and this book gave me way more than I bargained for. This is a good review.
Bruce is really thoughtful about his own psychological issues, workaholism, teetotalism, obsessiveness... definitely give it a read if you're into surprising biographies of high-performing nutters who will hustle to get the job done.
As a biography, for me - a programmer, musician, and fan - it's up there with 'The Autobiography of Malcolm X' (especially in terms of surprise) and 'Steve Jobs' (in terms of brutality).
