Slayer, Marilyn Manson and Bullet For My Valentine lead the bill for the second annual Rockstar Energy Drink Mayhem Festival, which begins July 10 at the Sleep Train Amphitheater in Sacramento, Calif., and wraps Aug. 18 at the Verizon Wireless Amphitheatre in San Antonio.
 
Jagermeister is sponsoring one of two second stages, on which Trivium, All That Remains, God Forbid and the liquor company's "battle of the bands" winner will perform. On the Hot Topic side stage, Cannibal Corpse, Job For A Cowboy, Behemoth, Black Dahlia Murder and Whitechapel will round out the bill.
 
Tickets for the 27-date North American shed tour go on sale April 24 via mayhemfest.com and livenation.com.
 
Last year's inaugural Rockstar Energy Drink Mayhem Festival featured Slipknot, Disturbed, Airbourne, Five Finger Death Punch, 36 Crazyfists, Machine Head, Black Tide, Suicide Silence, the Red Chord and Wall Of Jericho. The trek attracted nearly 340,000 concertgoers, according to organizers.
 
Rockstar Mayhem is produced by Warped founder Kevin Lyman, his partner on the Rockstar Taste Of Chaos tour John Reese, CAA's Darryl Eaton, and Jason Garner, CEO of global music at Live Nation. Following a model of tapping sponsors in unique and interactive ways, Mayhem was a finalist for the 2008 Concert Marketing & Promotion Awards.

"After last year's very successful package, we felt we needed to raise the bar higher and put together a package that hard music fans would love, and we feel like we have done that," Reese tells Billboard.com. "It also looks like I will be picking up a second job this summer as the lead bartender at the absinthe-laced parties for Manson and Slayer."
