Slipknot's fourth album has been christened "All Hope Is Gone" and will arrive Aug. 26 via Roadrunner. A first single and track list have yet to be announced.

"We have made an album that will show the road behind, the road ahead, and where we are as men," group member Corey Taylor says in a statement. "I think it's the best thing I've ever made. And I challenge anyone to prove me wrong."

Taylor previously described the new album to Billboard as a "very dark" cross between "Vol. 3" and 2001's "Iowa." "It has so much power in it and yet there are so many great spots for melody," he said. "It's a controlled chaos that hits you right out of the gate."

Lyrically, "Instead of bitching about what went wrong in my life, I'm bitching about what's wrong in life, period," Taylor said, noting that his vocals are much more melodic than before. "I got to the point where I was tired of pretending that I couldn't sing every time I made a Slipknot album, so this time I'm going all out."

Slipknot will co-headline this summer's 30-date Rockstar Energy Drink Mayhem tour, which begins July 9 at the White River Amphitheatre in Auburn, Wash.
