Foo Fighters were joined by Hives frontman Pelle Almqvist to cover AC/DC’s “Let There Be Rock” during their recent gig in Stockholm, Sweden. Before bringing out Almqvist, Grohl talked about his admiration for him, revealing that he even dressed as Almqvist and covered the Hives’ “Hate to Say I Told You So” at Foo Fighters’ Halloween 2002 gig in New York. “So tonight I thought it would be a good idea if we did a song together, one that we’ve never played with him before, but I think it makes perfect sense for this show,” Grohl said as the intro to Led Zeppelin’s “Stairway to Heaven” began to play before tearing into the 1977 AC/DC track, which Foo Fighters have frequently performed live since 2015. Foo Fighters released their latest album, Concrete and Gold, on September 15.
