I think we can all agree that at this point Slipknot have moved beyond being just a band, as their influence has reached the level of a subculture entirely its own. Now, if we're just talking musically, they've certainly made a dent in today's version of heavy sounds, and Day Of The Gusano documents their highly anticipated first show in Mexico from December 2015 on both DVD and CD (Blu-Ray version also exists).
Directed by Shawn Crahan (AKA Clown), the DVD unfolds like a documentary with plenty of interview footage alongside the music. Sure, the concert portion is there for the unwavering fans, full of fury and incendiary performances, but the warm, human part of the film is the documenting of a few fans and their journey to the show, as they discuss the strong bond between the music and their lives. We also get several pieces of the band exploring Mexico and absorbing its culture, and plenty of humble and appreciative discussion from Slipknot regarding their 'Maggots' (endearing term for a Slipknot fan).
