But Corey will still be there with Stone Sour.
Corey Taylor has revealed that Slipknot will not be playing this year's Knotfest.
Speaking to Billboard, the frontman had this to say...
"Nothing's being written, nothing's being done. Everybody's just doing their thing, which is fine.
"I think in a lot of ways your festival has to live past you, or it's not gonna live at all,
"If it has to live and breathe on your presence, then it's not a festival, and it's not for anybody else but you. And for us, it's always been more about the art and the music and everybody...
"That's why we put so much work into it to begin with, is to really make sure that it was stable and it was strong and the foundation was there."
He adds that his appearances at the festival will be with Stone Sour.
One date has been already announced for October 28 in Toluca, Mexico.
A U.S. date, again paired with Ozzy Osbourne's OZZfest, is expected to be announced July 10.
Stone Sour's new album 'Hydrograd' is out now, via Roadrunner Records. Check the video for 'Fabuless' below.
