Regarding the continuation of Slipknot, Taylor told "NME" Gray would want them to continue and he felt they should but he was ambivalent about returning to the band. Slipknot returned to touring in 2011, performing a small number of shows in Europe. They headlined the Sonisphere Festival and Rock in Rio alongside Iron Maiden and Metallica, and performed at Belgium's Graspop Metal Meeting. Donnie Steele substituted for Gray in the concerts; he was positioned behind Jordison and obscured from the audience's view.
