Not only is Slipknot's Iowa considered one of the biggest and most influential albums of the 2000s metal scene, apparently it can also help identify certain medical conditions.
Speaking with Revolver, Knot turntablist Sid Wilson recalls when he played Iowa for Papa Roach's original drummer, Dave Buckner, before it first came out. Upon listening to it, Buckner had a reaction that Wilson was very much not expecting.
"[Buckner] comes up on the bus and I think we were into maybe the third track," Wilson remembers. "And I just watched his face and he started getting uneasy, and he's looking around at the ground and stuff. And then he looks up and I'm looking at him, and his face collapses. One whole side of his face. And it drooped out like when you have a seizure."
Wilson adds that Buckner's "whole face collapsed and it just stayed down there."
"His eye, everything," Wilson shares. "The music collapsed his face."
Upon seeing Wilson's interview, Buckner reached out to Revolver to explain what had really happened to him.
"[Slipknot] played us the album in the mixing room with the volume cranked to 11," Buckner says. "I left the room with my ears ringing, and when I woke up the next day and the left side of my face was hanging off my skull, totally paralyzed! I thought I had a stroke during the night!"
During an emergency visit to the doctor, Buckner found out he had Bell's palsy, a nerve disorder that can cause paralysis in the face.
"Causes can include blunt force trauma, extremely loud noise, and, apparently, Slipknot!" Buckner says. "Slipknot music literally melts faces."
