The second stage will be feature Anthrax, The Devil Wears Prada, Asking Alexandria, As I Lay Dying, and Whitechapel when the 26 date North American tour kicks off on June 30th in San Bernardino, Ca. As for the special guest taking third slot, it won't be officially announced until March 5th but our news partner Banana1015.com speculates that the additional act will be Motorhead.

Members of Slipknot and Slayer reacted to the announcement. Slipknot frontman Corey Taylor said "You knew we'd be back. Now, you know we're coming. This will be a tour people will scarcely want to miss. It will definitely be a show to remember. Can't wait to see the states again from behind a mask."

Slipknot's, Clown adds "Slipknot is headlining this summer's Mayhem festival and it's going to be unlike anything you've ever felt, sensed, or seen. You miss this, you miss everything. Everyone seems to think that there's a chance we're gonna go away. This is the farthest thing from the truth. Stay sic and don't ever judge us."

"Mayhem 2012 might just be the last and greatest metal festival before the world ends!! So wreak havoc and go out in style!!" said Tom Araya of Slayer.

Slayer's Kerry King comments " We can't wait to get rolling on Mayhem 2012! Been 3 years since we played it last, and it's gonna be brutal!!! You can't go wrong with Slayer and Slipknot, pure f**king mayhem!!!!
