Grohl compared Eilish's momentum to that of Nirvana’s back in 1991.
The Foo Fighters frontman -- who has covered Eilish’s “idontwannabeyouanymore” with his daughter, Violet, before -- said the excitement surrounding the 17-year-old’s music reminded him of Nirvana in 1991.
“My daughters are obsessed with Billie Eilish,” he said during the conference. “The same thing is happening with her that happened with Nirvana in 1991. People say, ‘Is rock dead?’ When I look at someone like Billie Eilish, rock and roll is not close to dead!”
