Gehenna

Lead singer Corey Taylor (from Kerrang! July 19, 2008): "It deals with obsession from the person with the obsession's point of view. And wanting to let go of the facade and being true to yourself, as monstrous as it may seem. It's badass! Vocally, I'm doing some s--t that I've never done before and its f--king disturbing, but very beautiful at the same time."

Gehenna was the valley outside of the walls of Jerusalem at the foot of Mount Zion, which in Biblical times was a public rubbish dump. The names "Hell" and "Gehenna" were interchangeable.
