Slipknot has seen some significant changes and faced heartbreaking tragedy since the drop of their last record, All Hope Is Gone, in 2008. In 2010, bassist Paul Gray passed away due to an accidental morphine overdose; in December, Joey Jordinson, drummer, founding member of the heavy metal outfit its co-songwriter parted ways with his bandmates of 18 years, with Slipknot citing "personal reasons" as the cause for the split. 

In short, this has been a brutal few years for Slipknot, but the personal turmoil hasn't gotten in the way of their music. News of a new record leaked a couple of years back, and now they've finally posted "The Negative One" on their website, the first new material since All Hope Is Gone.

The name of the record and its release date remain unknown, but Knotfest will serve as the official debut of sorts for the new stuff: Knotfest, which takes place October 25 and 26 in San Bernardino, CA, will hand over a digital copy of the forthcoming record with every ticket.
