"Last year's inaugural Mayhem Festival tour was a definitive success, attracting nearly 340,000 incremental fans to our amphitheaters," said Jason Garner, Chief Executive Officer of Global Music at Live Nation, the tour's co-producer. "This year, the Mayhem team has delivered another great all-star lineup and we anticipate another huge success for Mayhem."

"I have good news and I have bad news to announce," declares Manson. "The good news is that I am completely aware now that our music and our Mayhem tour will have a negative, destructive influence on America. The bad news is that I don't give a f***."

Manson is currently in the studio working on his forthcoming album scheduled for release in May on Interscope Records. This highly anticipated record reunites Manson and Twiggy Ramirez for their first collaboration since Hollywood in 2001.

Summer 2009 will also see a brand new album from the mighty Slayer, who have already recorded three new songs and are slated to return to the studio in February to finish. Late last fall, Slayer made one of the new tracks, "Psychopathy Red," available as a free online stream to fans, and to date, the song has been Posted online at more than one million sites.

"We co-headlined with Manson once before, a couple of years ago," said Slayer's Kerry King, "so we all know what we're getting into. Manson and I probably drank a little too much absinthe on that tour, but we had a really good time hanging out and playing good music - we're looking forward to doing the same this summer on Mayhem."

Says Slayer vocalist/bassist Tom Araya, "We're looking forward to some summer mayhem and playing new sh*t!"

The Mayhem Festival is the brainchild of Kevin Lyman, John Reese and CAA's Darryl Eaton, the creative team behind some of the industry's most successful road jaunts, including the long-running Vans Warped Tour and the Worldwide Rockstar Taste of Chaos Tour.
