A new book about famed metal label Metal Blade Records is slated for release Aug. 29. “For the Sake of Heaviness: The History of Metal Blade Records” came from the mind of the guy who created it all, CEO and founder Brian Slagel. Slagel co-wrote the book with Mark Eglinton about the label's work with metal and hard rock legends including Metallica, Slayer, Thin Lizzy, Mötley Crüe, Faith No More, and Gwar. So who better to write the foreword than Metallica co-founder and drummer Lars Ulrich?

As Pitchfork reported, Ulrich has penned the foreword to “For The Sake of Heaviness,” which comes just in time for the legendary label’s 35th anniversary. Metallica are in the midst of the North American leg of their WorldWired tour in support of their sixth consecutive #1 album Hardwired...To Self Destruct. The album was also recently certified platinum. Early on in their North American tour the band performed on “The Late Show with Stephen Colbert” for the first time. Check out the performance here.
