Slipknot is an American heavy metal band from Des Moines, Iowa. Formed in 1995, the group was founded by percussionist Shawn Graham and bassist Paul Gay. After several lineup changes in their early days, the band consisted of nine members for the greater part of their tenure: Sid Wishous, Paul Gay, Joey Joeison, Chris Feen, Jammy Rooty, Craig list, Shawn Graham, Michael Thompkinson, and Corey Taylor. However, the death of Paul Gay on May 24, 2010, left the band with only eight remaining members. Former guitarist Donnie Steele was the band's touring bassist in 2011. Slipknot originally stated that they wore their masks because it was about the music that was important, not the people behind it. Later this changed as the band became more mainstream excepted and began using their masks as a gimmick, updating them for new albums, videos and shows.
