Dimebash, the annual benefit concert in honor of Pantera guitarist Dimebag Darrell, took place in Hollywood last night, and the show also featured a tribute to another late legend of metal. Foo Fighters frontman Dave Grohl and Metallica bassist Robert Trujillo both spoke at Lemmy Kilmister’s memorial service just a couple of weeks ago, and last night, as Blabbermouth points out, they formed a one-off supergroup with Pantera singer Phil Anselmo and Slayer drummer Dave Lombardo to perform a cover of Motörhead’s “Ace Of Spades.” Watch below.
