is running a contest that, frankly, we can't imagine anyone not wanting to enter. Not only could you win two tickets to see the Rockstar Energy Drink Mayhem Festival tour (headlined by Slipknot, with support from Slayer, Motorhead, Anthrax, and many more) near you, but you also win an autographed copy of the forthcoming Slipknot compilation Antennas to Hell, due in stores July 24!
