Slipknot will bring their annual Knotfest Roadshow to sea for the first time this summer with a stacked, head-banging lineup.

Knotfest At Sea, which was  first announced last November, is set to take place from August 10 to 14 in the waters around Barcelona on Norwegian Jade and is being described as a “voyage that will awaken your darkest senses.” Now, they’ve announced a handful of artists who will join them at sea including the metalheads of Anthrax, Behemoth, Devildriver, Sevendust, and Skindred. Ho99o9, Higher Power, and Sleep Token will also take the stage, with more artists set to be announced in the coming months.

“DevilDriver is extremely honored to be asked to play the first KnotFest At Sea cruise!” Devilrider frontman Dez Fafara said in a statement. “We cannot wait to sail the high seas together with SLIPKNOT and this killer line-up of bands. So raise the Skull & Crossbones and prepare for a party at sea.”

Slipknot will perform two headlining sets during the event and will also stick around for a live Q&A. Fans can also look forward to an exclusive DJ/MC set from Sid, a whiskey tasting and discussion with Clown, a signing with Mic Thomson, a drum workshop by Jay Weinberg, and a bass clinic with VMan. Throughout the ship, 20 years of Slipknot memorabilia will be showcased for viewing.

Although Slipknot’s tour is coming to an end soon in Europe, they’re hitting the road again this summer for the Knotfest Roadshow across North America with A Day To Remember, Underoath, and Code Orange. They’ll be touring in support of their 2019 No. 1 LP We Are Not Your Kind, which features singles “Unsainted” and “Solway Firth.” Find tickets to the tour here.
