As winter begins to fade and spring gets closer, summer's big touring festivals begin revealing their lineups and dates. As expected, Rockstar Energy Drink Mayhem Festival 2011 is pulling no punches this summer with Disturbed, Godsmack and Megadeth leading the top-notch lineup.

"It's been years since we shared the stage with Godsmack and we've been wanting to team up with them and join forces for a long time," Disturbed guitarist Dan Donnegan said in statement. "Megadeth has been a big inspiration to us and we are looking forward to the other bands rounding out what seems to be a solid bill."

Joining the heavy hitters on the main stage are In Flames, Machine Head and Trivium. These three tech-metallars have all worked their way up the ranks and will surely be must-see bands at this year's loudest traveling festival.

The Jägermeister stage will host performances by Kingdom of Sorrow, Red Fang and Unearth -- who are expected to have a new album about by tour time. The festival's Extreme Stage will unleash performances from Suicide Silence, All Shall Perish and Straight Line Stitch.

On the July 9 show in San Bernardino, Calif., Megadeth will not be appearing. But the mighty cartoon metallers Dethklock will take their place. "There is nothing more brutal than horrible hot putrid disgusting summer; why not make it just a little more brutal, right?" 'Metalocalypse' co-creator and Dethklock frontman Brendon Small said. "We are super honored to be a part of this amazing lineup! I can't wait!"

That night, thrash legends Testament will take the stage in lieu of an absent In Flames.
