I've read a few. Scar Tissue by Anthony Kiedis, Star Man by Michael Francis, a bunch of Doors/Morrison bios and Crosstown Traffic.
I'm about to start on The Dirt: Confessions of the World's Most Notorious Rock Band by Tommy Lee. Following this, I'll probably try to get my hands on Walk This Way: The Autobiography of Aerosmith.
Are there any others that you'd like to recommend?
