The biggest metal festival in North America will return in November of this year. Ozzfest Meets Knotfest, the symbiotic clash of the great Ozzy Osbourne and his friends in Slipknot, just released its eclectic lineup. The two day festival will kick off with Ozzfest on Saturday, November fourth, and Knotfest the next day on the fifth. The concerts will be held at Glen Helen Amphitheater And Festival Grounds in San Bernardino, CA, and there will be a special pre-fest kickoff on Friday, November 3 for all ticketed campers.

Ozzy Osbourne released a statement today, saying, “Last year’s show with Black Sabbath was just incredible and I’m thrilled to be coming back this year with Zakk, Tommy, Blasko and Adam to headline the 21st anniversary of Ozzfest.” Last year’s show included bands like Disturbed, Opeth, Megadeth, Children of Bodom, Hatebreed, and the great Black Sabbath. The previous festival had over 75,000 attendees who came to celebrate Osbourne’s first solo show in L.A. in more than six years. This year, he’s at it again, along with his longtime guitarist, Zakk Wylde.

Knotfest began on its own in August of 2012. This year, the long running festival teams up with Ozzfest once again, to bring fans twenty-four collective hours of heavy metal in the hot San Bernardino sun. Performances will run from 11 a.m. until 11 p.m. Because of the hot weather and graphic nature of the festival, children ten years or younger will not be permitted.

Corey Taylor of Slipknot released a statement explaining Slipknot’s absence from the lineup. “Knotfest was never supposed to be exclusively about Slipknot. It was always about the things that fueled the spirit of Slipknot: music, art, passion, insanity, and the tribes that give it power. So it would make sense for Knotfest to carry on these ideas, even without Slipknot.”

The multi-stage, two-day camping event will include over forty acts. Tickets can be purchased July 14th on Ozzfest.com and Knotfest.com, and will range from $29 for a single day ticket to $239 for two-day passes.
