Slipknot is an American alternative/nu metal band from Des Moines, Iowa. Formed in 1995, the group was founded by percussionist Shawn Crahan and bassist Paul Gray. After several lineup changes in their early days, the band consisted of nine members for the greater part of their tenure: Sid Wilson, Paul Gray, Joey Jordison, Chris Fehn, Jim Root, Craig Jones, Shawn Crahan, Mick Thomson, and Corey Taylor. However, the death of Paul Gray on May 24, 2010, left the band with only eight remaining members. Former guitarist Donnie Steele will be the band's touring bassist in 2011. Slipknot is well known by their attention-grabbing image, aggressive music style and chaotic live shows. The band had somewhat of a meteoric rise to success following the release of their self-titled debut album, Slipknot, in 1999. The 2001 follow-up album Iowa further increased the band's popularity. After breaking for their first hiatus, Slipknot returned in 2004 with Vol. 3: (The Subliminal Verses) and once again in 2008 with their fourth album All Hope Is Gone, which debuted at the top spot on the Billboard 200. The band has also released one live album, 9.0 Live, and four DVDs. Slipknot hosted their first annual music festival, called Knotfest, which was held on August 17, 2012, at Mid-America Motorplex near Pacific Junction, Iowa and August 18, 2012, in Somerset, Wisconsin. The long awaited fifth studio album is in the works and is expected to be released in 2014. Taylor has described the forthcoming album as "very dark" and a cross between Iowa and Vol. 3: (The Subliminal Verses). On February 27, 2014, all of Slipknot's social media outlets and official website content was blacked out. No reason for this has been said, however the band are still recording their next album.
