SLIPKNOT, the Grammy Award winning hard rock machine from of Des Moines, IA is back. The band will release its fourth album, All Hope is Gone, on Roadrunner Records on August 26, 2008. The album was recorded this spring in Slipknot's home state and is co-produced by the band and Dave Fortman.

"The nine" will spend their summer laying waste to arenas in North America as they headline the first annual Rock Star Energy Mayhem Festival. As Slipknot's first tour in three years, these dates are sure to bring the band's legion of diehard fans, affectionately dubbed "maggots," out in full force.

All Hope is Gone is more of a statement than a record. Corey Taylor comments, "Every album we have made is a statement about that space in time. I think this era is the most mature, most beautiful and the most powerful. We have made an album that will show the road behind, the road ahead, and where we are as men. I think it's the best thing I've ever made. And I challenge anyone to prove me wrong."

The album promises to blend elements of 2004's Vol. 3: (The Subliminal Verses) and 2001's Iowa, while adding a perspective, freshness and depth that only three years apart can bring. The first single "Psychosocial" will be delivered to radio on June 30 and will be available digitally on July 1. A complete track listing will be announced shortly.

Slipknot is the ever-evolving definitive voice in hard rock music. They are pioneers of an alternative metal scene, where scarring riffs and thunderous percussion are punctuated by vocals, which seamlessly shift from brutal to melodic within a breath. The band's previous studio albums, Slipknot, Iowa, Vol.3:(The Subliminal Verses) have all been certified platinum or better, as have their DVDs, Welcome to Our Neighborhood, Disasterpiece and Voliminal: Inside the Nine. The double live 9.0: Live holds a gold certification.

As previously reported, an audio sample of the new Slipknot song called 'All Hope Is Gone' is currently available at Amazon.com. The single - which comes off the forthcoming new album - is due out on June 20th via Roadrunner Records.
