Masked Slipknot star Corey Taylor has mixed emotions about performing at his first Ozzfest in 1999 - because he had to eat his own vomit.
The energetic frontman was often so dehydrated and hot behind his mask during performances, he'd throw up and have to spend the rest of the set trying to sing through sick.
He tells Revolver magazine, "It was so hot and I was raging so hard that I threw up in my mask and had to eat the puke because there was nowhere to spit it (out).
"I broke my mouth so many f**king times just coming up too hard on the mic. I'd go from swallowing blood to puking and having to swallow that."
