Slipknot has put out a casting call for a new music video, inviting fans to a shoot in Los Angeles on Friday, October 5th. The message did not provide any more details about the clip, but was captioned “Slipknot 20th Anniversary,” presumably referring to the 20th anniversary of the release of the band’s self-titled 1999 major label debut album. Fans wanting to participate in the music video shoot are being asked to e-mail their name and age to Those who are under the age of 18 will need to provide a copy of their parent/guardian’s photo identification and a release form signed by the parent/guardian. The masked nine-piece band also has plans to regroup early next year and begin working on its sixth studio album, which will follow up 2014’s .5: The Gray Chapter.
