Yesterday (8), we noticed Slipknot were up to something. At that time, we hoped it would be a Knotfest 2017 announcement or even a Knotfest in Mexico event. However, today, the band dropped the news with a brand new trailer revealing their forthcoming documentary. Day of The Gusano was filmed during 2015’s Knotfest in Mexico City and it receives a one-day-only worldwide theatrical release on September 6th. The story moves between the band’s lively animated performance and their devoted maggots.

Check out the trailer:
