Slipknot have put out a casting call asking fans to appear in their new music video.

Corey Taylor and co will mark their 20th anniversary next year by re-releasing their self-titled debut LP, and on Wednesday (26.09.18) the 'Duality' hitmakers teased a new promo which they are filming on October 5 in Los Angeles, which they want their loyal following to get involved in by signing up to appear as extras.

Alongside the post, they tweeted: ''#Slipknot 20th Anniversary

Music Video Casting Call

Los Angeles, CA // October 05

Email name & age: (sic)''

Shawn 'Clown' Crahan, the Grammy-winning band's percussionist and co-founder, recently confirmed plans for the band to re-release their fourth LP 'All Hope Is Gone' as well.

The 'Before I Forget' rockers are believed to be working with Ross Robinson, the producer of their LP 'Iowa' on their new album, also due out in 2019, and recently teased the new material is in the same vein of the 2001 album.

Corey said: ''It's only in the demo stages right now, however we have very serious, tentative plans - and I say that because the best way to make God laugh is to announce your plans out loud - to go into the studio at the beginning of next year and get this fucker going.

''We have 16 songs written right now, and they are f***ing dangerous. I loved '.5 [The Gray Chapter]', but this album, to me, makes '.5' look like nobody's business.''

Last year, Corey's bandmate Clown suggested the LP could end up being their last.

He admitted: ''I feel like this could be it for me. We're all getting older. I never like telling anyone like, 'Hey this is it!' Because I don't have to, f**k everyone. But like I've said, I've been reflecting and there's a lot of hard things that I could say about friends, brothers ... We're good, but it's a big world. I've done enough work, I've produced and done remixes and art and performed, I've done enough where while I was in it none of it was registered.''
