(Part 2) Top products from r/Metal101

Here are a few I've read and really enjoyed.

• Marilyn Manson - The Long Hard Road Out of Hello. While I am not a fan, this is a really interesting read. Bryan is very eloquent.
  
• Rex Brown - Official Truth, 101 Proof: The Inside Story of Pantera. Not the most flattering book about of one of my favorite bands, but honest and heartfelt. I consider this a must read for Pantera fans.
  
• The Bloody Reign of Slayer - again a great account of Slayer's history up to about 2007. My only gripe is the author sort of does a review of each album and sometimes he's overly critical.
  
• Eddie Trunk's Essential Hard Rock and Heavy Metal - This book has SO much information and is worth a read. Eddie is a true fan and gets it right 100% of the time.
  
• Sully Erna - The Paths We Choose: A Memoir. While I am not a huge Godsmack fan, I like their earlier stuff and to this day, Godsmack is one of the best live bands I've ever seen. Any musician who is thinking about trying to break out should read this.
  
• Choosing Death (linked many times in other responses), man, a history lesson totally worth reading...know your roots ;)

Rat Salad is a great biography about Black Sabbath's Ozzy years. The book not only serves as a great lesson about Black Sabbath's history. It also is a great in-depth look at the songs themselves. It's like having a class on the music theory behind Black Sabbath's music. He also provides context for the years albums were released and he includes his own connection to Black Sabbath. It's a great book if you are a Black Sabbath fan. Link to the book on Amazon: http://www.amazon.com/Rat-Salad-Sabbath-Classic-1969-1975/dp/0312367236

I have a few recommendations for you:

• Lords of Chaos: Pretty decent (if not slightly sensationalist) story of the Norwegian BM scene. It also covers Dissection, Absurd and a few other notorious groups.
  
• Swedish Death Metal: A fantastic and exhaustive look into the early Swedih death metal. Lots of super influential bands are covered.
  
• Sound of the Beast: I read this about ten years ago, so it's distant for me. I remember enjoying it. It covers a lot of the early scene very well. Lots of coverage on Motorhead and NWOBHM. It also follows Metallica's early career.

Bang Your Head: The Rise and Fall of Heavy Metal It covers the history of "mainstream" metal from the late 60s and early 70s to the fall of hair metal in the 90s, but doesn't cover any of the underground Death and Grind movements in the 80s and 90s. For that, I'd recommend Choosing Death which has already been mentioned.

I am Ozzy is Ozzy's autobiography that recounts all his crazy stories from his day's with Sabbath, to losing Randy, to getting a reality show, and so on. Good read that gives you a decent perspective on how huge and successful that guy was (and still is).

Crazy Train: The High Life And Tragic Death Of Randy Rhoad is a biography that explains the full extent of Randy's genius. It's also rells the story of how a suburban kid got swept up into the rock star lifestyle.
