a statement: "While no one is willing to provide evidence that would prove unfavorable to Disney, sources close to events have suggested that Machine Head remains on a "banned list", and while Dethklok, All That Remains and Black Dahlia Murder will still be allowed to play, the corporate powers at Disney have refused to allow Machine Head to perform." On November 13, 2012, Machine Head exited their North American tour with Dethklok, All That Remains and Black Dahlia Murder due to matters completely beyond their control. Frontman Robb Flynn needed emergency surgery. Flynn had planned to go under the knife in January after completing the tour as he has been playing through the pain of a double inguinal hernia since the tour started in October. He had hoped to continue the tour despite extreme discomfort, but it became too difficult to continue on. Flynn underwent surgery on Wednesday, November 14 in Minneapolis before returning home to California to recover, rest and recuperate. Machine Head rejoined the tour in Portland, Oregon. This tour was the last with Adam Duce. Tour dates A^ Headline shows, non Soundwave festival dates. B^ Opening for Metallica.
