Loudwire reports that Weezer frontman Rivers Cuomo introduced the song as a “teaser” for Grohl’s current band Foo Fighters, who were headlining the festival. It was one of five covers that the band elected to play, and one of only two that wasn’t off their covers album, Weezer (The Teal Album). Cuomo has talked extensively about his love for Nirvana, saying in a 2014 Rolling Stone interview that he felt like he was “Nirvana’s biggest fan in the Nineties.”
Grohl acknowledged the tribute in the middle of Foo Fighters’ set, dedicating their song “Big Me” to Weezer in return.
“I was backstage and I heard Weezer play the ‘Lithium’ song,” Grohl told the crowd. “I gotta be honest, I cried a little bit. I did! I miss playing that song. I miss it, so I’m happy to hear Weezer play it again. So this one goes out to the sweet Weezer.”
At that same fest, Grohl teased new music from the Foo Fighters. “We go home next week and we start making a new Foo Fighters record,” he said during the band’s set.
Nirvana’s seminal live acoustic album, MTV Unplugged in New York, will be reissued in November on a 2-LP vinyl, with newly released rehearsal versions of “The Man Who Sold the World” and other songs from the set. This past week, Foo Fighters released a rarities EP that includes live renditions of Arcade Fire’s “Keep the Car Running” and Dead Kennedys’ “Holiday in Cambodia.”
Along with Green Day and Fall Out Boy, Weezer are set to embark on an extensive stadium tour in summer 2020.
