It's time to bring the heavy! Summer is fast approaching, which means it's time for the announcement of the annual Rockstar Energy Drink Mayhem Festival lineup, which this year features the mighty Slayer in the headline spot.

The band will be supported on the Main Stage by King Diamond, Hellyeah and The Devil Wears Prada. The Victory Records Stage will find Whitechapel, Thy Art Is Murder, Jungle Rot, Sister Sin, Sworn In, Shattered Sun, Feed Her to the Sharks, Code Orange and Kissing Cadence all rocking the festival, as well.

Slayer guitarist Kerry King states, "I don't know if the third time will be a charm, but it will definitely be hellish. Slayer and King Diamond onstage for the first time together in the States -- never has Mayhem been more evil. Don't f---in' miss it!"

Meanwhile, King Diamond adds, "This is going to be one hot and hellish summer. Slayer and King Diamond on the same stage -- it does not get more devilish than this! We will be putting on a one-hour set with the full King Diamond stage production. As for a set list, I'm not gonna reveal that here, but it will be built around Dreams of Horror. The Puppet Master will be there with Grandma, and we will even go as far back in time as to 1777 (hint). You're all in for one hell of a show if you come to this Sabbath!”

Tickets for this year's event go on sale beginning April 17 at 10AM local time and there's an all-in $19.99 general admission festival ticket option available during the first 72 hours at most stops while supplies last. Only Boise, Denver, Council Bluffs and Milwaukee will not be taking part in the promotion. For more info, visit the festival website.
