Slipknotstill haven't announced who's been touring with them as a replacement for fired percussionist Chris Fehn-- and it seems like they're having fun trolling fans about it.
A fan posted a photo from a recent European festival gig on Reddit showing the percussionist standing over his kit, and written on one of the drumheads is "Who is the new guy?" And below that is a drawing of a head with a question mark over the face.
The only public comment on the new member's identity came from Shawn Crahan back in May, who said it was "nobody's [bleeping] business."
