In 2003, Slipknot moved into The Mansion to work on the album. Initially, the band was unproductive; Corey Taylor was drinking heavily. Nevertheless, they wrote more than enough material for a new album—the band’s first to incorporate more traditional, melodic song structures, guitar solos, and acoustic guitars. The album received generally positive reviews. It peaked within the top ten in album sales across eleven countries, and went Platinum in the United States. The band also received the Grammy Award for Best Metal Performance for the song “Before I Forget.” Roadrunner Records have listed the music video for “Duality” as the best music video in Roadrunner history.
