Slipknot is an American heavy metal band from Des Moines, Iowa. The band was founded in September 1995 by percussionist Shawn Crahan and bassist Paul Gray.
The band has said the idea of wearing masks stemmed from a clown mask that Crahan took to rehearsals when the band first started. Crahan later became known for his clown masks, adopting the pseudonym “Shawn the Clown”. The concept developed; by late 1997, the band decided every band member would wear a unique mask and matching jumpsuit. Taylor said in 2002, “it’s our way of becoming more intimate with the music. It’s a way for us to become unconscious of who we are and what we do outside of music. It’s a way for us to kind of crawl inside it and be able to use it.”
