There's a lot going on in Slipknot's world these days. Not only are they getting ready for their new album, '.5: The Gray Chapter,' but they've also got the U.S. edition of Knotfest coming up.

In advance of their new album, the band has unleashed yet another new song. Check out 'XIX' at this location. The track, which serves as the album opener, builds in intensity as the song moves forward, then drops off at the end, appearing to be a transition into another track on the forthcoming release.

Meanwhile, Slipknot's U.S. edition of the 2014 Knotfest is nearly upon us and fans can start mapping out their fans as to who they want to see. That's because the organizers have revealed the set times for the music weekend.

This year's Knotfest is taking place over three days -- Oct. 24-26 -- at the San Manuel Amphitheatre and Campgrounds in San Bernardino, Calif.
