I finished "The Heroin Diaries: A Year in the Life of a Shattered Rock Star" by Nikki Sixx.
Nikki is the bassist and song writer for Mötley Crüe. It is pretty amazing.
I am now reading
"The Dirt: Confessions of the World's Most Notorious Rock Band" which is also about Mötley Crüe and others associated with the band. This was written before The Heroin Diaries.
After I read this, a book about Slash, the bassist for Guns&Roses has caught my eye.
