Rockstar Energy Drink Mayhem Festival has announced the addition of MOTÖRHEAD to the 2012 lineup. This marks the first summer tour that Motörhead has taken part in for several years. The legendary metal veterans join the already stellar 2012 main stage lineup, featuring multi-platinum Iowa cult metal groundbreakers SLIPKNOT in the headlining position, as well as legendary thrash metal kings SLAYER — both returning to the Rockstar Energy Drink Mayhem Festival for a second turn at pummeling fans.

Motörhead frontman Lemmy Kilmister commented, "Well, we're used to mayhem in this band, so it's kind of a family tradition! Bring it!"

In other news, Sumerian Records is joining the Rockstar Energy Drink Mayhem Festival. Headbang For The Highway will be presenting the Sumerian Records Stage at the Rockstar Energy Drink Mayhem Festival this year. Sumerian Records, who are known for some of the most cutting-edge bands in heavy music today, will be bringing UPON A BURNING BODY, I THE BREATHER and one more act (to be announced) along for the ride. The fun doesn't end there, as Headbang For The Highway will be holding contests all over the US for unsigned bands to win opening spots on the Sumerian Records Stage at the festival.

The Rockstar Energy Drink Mayhem Festival will make a 27-date trek across the US beginning on June 30th at the San Manuel Amphitheater in San Bernardino, California. The headlining slot on the main stage will be occupied by Iowa legends Slipknot. Next up will be legendary thrash metal kings Slayer and Motörhead will be playing in the third slot. The main stage will also spotlight a ferocious mix of today's best artists in a rotation, including THE DEVIL WEARS PRADA, AS I LAY DYING and ASKING ALEXANDRIA.

In 2012 the tour has upgraded the production on the festival stage and this year the Jägermeister Stage will feature a special headline set by metal masters ANTHRAX supported by a rotation of THE DEVIL WEARS PRADA, AS I LAY DYING and ASKING ALEXANDRIA, along with WHITECHAPEL, HIGH ON FIRE and the Jägermeister opener.
