“A home show is always insane, but a home ‘Knotfest’ show will be on a whole other level,” Slipknot‘s Shawn “Clown” Crahan said in a statement. “Prepare. See you soon for the new reality. Stay (sic).”

Slipknot are currently back in the studio working on new music, with the band set to follow up their 2019 album ‘We Are Not Your Kind’.

Speaking last week, “Clown” said that Slipknot were in the process of “making God music” in LA.

“We search our souls, so we believe that you’re gonna love it because we love it, I guess,” he said in reference to the new material. “It’s different.

“But I’ll tell you: I’ve never heard [frontman] Corey Taylor like this right now — I just never heard him like this. I feel full circle.”
