On last weekend's episode of Doctor Who, Corey Taylor provided the roar for an evil alien warlord called the Fisher King. In case you missed the episode, you can watch the Slipknot and Stone Sour frontman practice his menacing bellow in a behind-the-scenes clip on YouTube.
The clip also includes Taylor walking around and exploring the Doctor Who set. Taylor's a well known Whovian -- that's a of the long-running British sci-fi TV series.
"I've been a fan since I can remember," Taylor says in the video. "The cool thing is that now I've passed that on to my son."
Taylor will return to roaring with Slipknot Tuesday, October 13, when the band embarks on the fall leg of their North American tour. The trek concludes with Slipknot's headlining set at Knotfest on October 25.
