Watch Corey Taylor and Zakk Wylde's Epic Cover of Black Sabbath's "Fairies Wear Boots"

Following yesterday's press conference announcing the "Ozzfest Meets Knotfest" mega-festival, Zakk Wylde's Black Sabbath cover band Zakk Sabbath took to the stage at the Palladium in Hollywood. The band, which also features Rob Zombie bassist Blasko and and Danzig/Queens of the Stone Age drummer Joey Castillo, was joined by Slipknot's Corey Taylor (in mask but sans jumpsuit) for a rousing rendition of "Fairies Wear Boots." "Ozzfest Meets Knotfest" is scheduled to take place September 24th and September 25th at the San Manuel Amphitheater in San Bernardino, California.
