For something completely different, try Dirt about/by Motley Crue. I am no fan of their music, but someone gave me this book and it was very interesting. Graphic at times, but also very sensitive and even gutwrenching at others. And suprisingly well written. A good look into the 80s rock/metal scene.
Also, who's read the Eric Clapton autobio? It's gotten some rave reviews, I haven't looked at it yet though.
And I'm sure many have read Standing in the Shadows of Motown. That's another one I need to get to.
