Slipknot's new live album and documentary Day Of The Gusano is out this Friday, and the film takes a look at the setting up and performances at Knotfest Mexico City on December 15. This was the first time the band ever played Mexico City, and the film is directed and edited by Shawn "Clown" Crahan.
Slipknot has now posted a live video of the song "Psychosocial," and if you've heard pretty much any Slipknot live material at all ever, you'd know it's damn good. Day Of The Gusano is available as both a film and as a live album, and you can pre-order it in either format (or both) here.
