Watch Dave Grohl’s daughter sing with Foo Fighters at LollapaloozaMon, August 2, 2021 by ABC NewsSHARE NOW Kevin Mazur/Getty ImagesHomeMusicRockWatch Dave Grohl’s daughter sing with Foo Fighters at LollapaloozaFoo Fighters had a new lead singer — temporarily — on Sunday for their set at Lollapalooza: Dave Grohl‘s 15-year-old daughter.Violet Grohl joined her dad and his band mates to sing “Nausea,” by pioneering L.A. punk band X. In April, Violet performed the song on ABC’s Jimmy Kimmel Live!, backed by her dad, his ex-Nirvana bandmate Krist Novoselic, producer Greg Kurstin, and Mr. Bungle drummer Dave Lombardo. They recorded the song for Grohl’s documentary, What Drives Us.Sunday was also the seventh birthday of Grohl’s daughter, Ophelia, and after leading a “Happy Birthday” singalong for her, Grohl introduced Violet by saying, “If you stick around long enough, maybe your daughter will join your band, too. So since my daughter Violet Grohl is now in the Foo Fighters, we thought, ‘Why don’t we come out and sing a song for Lollapalooza tonight?"”Dave described Violet as “the most bad-a** person I know in my life,” and boasted that “she likes to listen to the punk rock music that I like to listen to.” After claiming that he and X drummer DJ Bonebrake are related — which may actually be true — he then let Violet take the mic for “Nausea.” She acquitted herself admirably in true rock-star style, and seemed totally unfazed by the massive crowd.Foo Fighters’ tour continues August 3 in St. Louis, MO.(Violet’s song with the band starts at 1:32:18 into the video.)Copyright © 2021, ABC Audio.
