Sid Wilson, the DJ for metal band Slipknot, broke both of his ankles last week.
The band, who release their fourth album 'All Hope Is Gone' this August, had just started a US tour when Wilson misjudged a landing as he leapt from a drum riser.
Percussionist Shawn Carter said: "He had to take his cast off last night, and I'm telling you, I couldn't even look at his feet. Both his feet were black and blue - and deep. The bruises go, like, two inches in."
However, the show goes on for these tough metal types, as Carter continued: "He's up there every night, no problem. He's so out of his mind, he's got a big bruise on his face because he's not used to slamming his head in a wheelchair. So he's got a huge bruise on his face from smacking his head into his tables. It never ends. You think you're out of it, and then you're back in, on some other painful level."
