Today (Aug. 29), Metal Blade Records and BMG have released For the Sake of Heaviness: The History of Metal Blade Records, written by label founder and CEO Brian Slagel with Mark Eglinton, and featuring a foreword by Metallica's Lars Ulrich.

Celebrating the storied label's 35th anniversary, the book is an inside look at how Slagel built Metal Blade from a one-man operation in his mom's non-air-conditioned garage to the preeminent international home of heavy music that it is today. Currently it's sitting in the top spot as the best selling metal book on Amazon.

An exclusive box-set is available here, and along with the book it comes with a For the Sake of Heaviness cassette (track listing below), a Metal Blade Records 35th anniversary bookmark and a bookplate autographed by Slagel.

“I have been asked many times about doing a book about the history of Metal Blade and it just seemed like a cool thing to do to document the 35th anniversary," Slagel says in a statement. "You never really stop to think about a lot of this stuff, so doing the book is a great way of looking back at how many awesome things have happened to me and Metal Blade. We have had a long relationship with BMG and with their new move in book publishing, it all seemed like perfect timing. Being able to work with their team really made the final decision to actually do the book. I am really happy with the way it came out and I hope everyone out there enjoys it as well!”

For the Sake of Heaviness pulls back the curtain to reveal the definitive look at how Metal Blade began, what they've accomplished, and where they're going. Slagel reveals the early advice he gave that helped guide Motley Crue's career; how he helped Metallica replace their bassist -- twice; his detailed work on Thin Lizzy and Alice Cooper re-issues; his behind-the-scenes role in the careers of Slayer, GWAR, Mother Love Bone, Alice in Chains, Faith No More, Goo Goo Dolls, and Lamb of God.
