Slipknot. 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 brought to you by MusicScreen, entitled Day Of The Gusano. The 90-minute documentary is to be premiered in more than a thousand screens across the world as a 'one night only' cinematic spectacle on September 6th. Watch a trailer below.

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. Confirmed cities and ticketing for the screenings will be announced in July. Sign up to receive dates and details at this location.

Talking about the movie, Clown tells us, "Slipknot still has dreams for itself. Finally playing Mexico was one of them. It's been a surreal life of rock and roll for Slipknot and the fact that the dreams still go on for us is simply incredible. Thank you."

Guitarist Jim Root continues, "We had such a great time at Knotfest Mexico... Not only with all the friends and bands that were there, but with the fans and the crowd we had to document it with. Now we get to share it with the world."

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.

To tie in with the movie announcement, Slipknot also launch their #AskSlipknot campaign. Fans are asked to submit their questions to the band on either Facebook or Twitter, using the hashtag, #AskSlipknot, and a selection will be chosen by the band to answer as part of the cinematic screening event. Submit your questions before 13th June in order to be in with a chance of getting your question included.
