“Strap yourself in and hold on tight, cuz this ride goes reeeeeal fassst this summer,” exclaims GODSMACK vocalist Sully Erna. “Godsmack/Disturbed, Mayhem Festival!! Can't Fu@?kin' wait!!!”

Mainstage guitarist Dan Donnegan of DISTURBED emotes, “DISTURBED is looking forward to being part of the biggest summer tour in the U.S. this year. 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 longtime. 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.”

Also, mainstage performer MEGADETH’s lead guitarist and frontman Dave Mustaine adds, “This is going to be a helluva hot summer, and you can get ready for true Mayhem this year.”

“MACHINE HEAD are thrilled to once again be a part of what has become the undisputed king of metal and rock festivals in the U.S., MAYHEM,” states MACHINE HEAD frontman and guitarist Robb Flynn. “Our run headlining the JAGERMEISTER stage in 2008 was one of the wildest and most inspiring tours we have ever been a part of. We became friends with so many great bands and Mulisha dudes. We all partied, and rode what would become an incredible wave of momentum for MACHINE HEAD. The vibe on the tour was filled with an impressive amount of goodwill due to the attention to detail and hard work of John Reese and Kevin Lyman. MACHINE HEAD will do everything in our power to make this f*&#ing huge!! Bring on the summer!”

“Metal is ALIVE and WELL in 2011,” states tour producer John Reese. “Each year the tour gets bigger and better and 2011 is no exception. This group of artists this year are going to apply a big, bad, metal shellacking for the fans across the USA and Canada.”

“ROCKSTAR ENERGY DRINK MAYHEM FESTIVAL 2011 is a true mix of molten veterans and smoldering up-and-comers, who are bringing their A games and giving the fans nothing less of an amazing day,” adds tour producer Kevin Lyman.

Live Nation is co-producer of the tour and will promote the festival nationally. Perry Lavoisne, SVP North American Touring for Live Nation, states, “The Mayhem team has delivered the best live metal line-up possible for four years in row, while creating a highly visible brand and value for fans of metal and hard rock. We anticipate another stellar run with DISTURBED, GODSMACK, MEGADETH and all the other bands uniting metal fans at every tour stop.”
