Slipknot's Corey Taylor and Shawn Crahan (who wears the clown mask) featured on a BBC 'Artsnight' documentary about "stepping out of our psychological skins" and talked about wearing their masks, NME reports.

Some members of the metal band known for their visual imagery still rarely appear in public without their masks, and the Artsnight show - which aired on February 5 on BBC Two - saw Crahan and Taylor discussing the role those masks play. In a trailer for the show, Taylor says of the masks "when it comes to this, all bets are off. You can really let that animal off the chain as far as you really want to go."

Crahan, meanwhile, argues that none of us "really see ourselves," and that the mask allows him to be more authentic.

Taylor surprised fans last week by saying he'd like to work with Eminem. Whilst talking of dream collaborations, he said:

"Everybody from Trent Reznor - I would love to work with Trent - to… I was just thinking about this the other day… I would love to do something with Eminem."

"I would love to trade some stuff back and forth with him, because I love the way he writes and the way he flows and the attitude; you know, the emotion that's in it. And I'm very, very attracted to that. And I would love to do something where we kind of go back and forth. Will it ever happen? Probably not. But, you know, it's still a dream."
