CD + DVD edition. A genuine sonic phenomenon, a nine-piece force of nature and one of heavy music's most important, recognizable, uncompromising and creatively ingenious bands. Yet to their millions of fans across the world, affectionately known as maggots, Slipknot aren't just a group, they're also a counterculture and a way of life. Those fans play an important role in a new documentary entitled Day of The Gusano. Directed by Slipknot's own M. Shawn Crahan, AKA Clown, Day of The Gusano documents the Iowa band's first ever visit to the country in December 2015 and features exclusive interviews with Slipknot's members talking about the importance of their fanbase and the band's long awaited first ever show in Mexico City. Day of the Gusano also chronicles the rabid devotion of the Mexican maggots and sees the band hearing personal, emotive stories from some of their fans, all interspersed with footage from Slipknot's incendiary live show at the inaugural Knotfest Mexico. The film features a full surround soundtrack, so you'll not only hear the show, but you'll feel it as if you were actually there.
