Mayhem 2011

Mayhem Festival 2011 was the fourth-annual Mayhem Festival founded and created by Kevin Lyman. 2011 was the first year that the festival used a rotating main-stage slot. Machine Head initially opened the Main stage until July 20, Trivium opened from July 22 to August 2, and In Flames  took over from August 3 until they left the tour. When one band opened the main stage, the other two bands headlined on the J├Ągermeister Mobile Stage and the Revolver Stage.
