Slipknot is an American heavy metal band from Des Moines, Iowa.

The band was founded in September 1995 by percussionist Shawn Crahan and drummer Joey Jordison. After several lineup changes in its early years, the band settled on nine members for more than a decade: Corey Taylor, Mick Thomson, Jim Root, Paul Gray, Craig Jones, Sid Wilson, Shawn Crahan, Chris Fehn and Joey Jordison. Gray died on May 24, 2010, and was replaced from 2011–2014 by former guitarist Donnie Steele. Jordison left the band on December 12, 2013. Steele left during the recording sessions for .5: The Gray Chapter. The band found replacements in Alessandro Venturella on bass and Jay Weinberg on drums. After the departure of Jordison, as of December 2015 the only founding member in the current lineup is percussionist Crahan; the other remaining members of Slipknot (with the exception of Weinburg and Venturella) have been members since the release of the band's 1999 eponymous debut album.
