It’s not the first time they’ve covered the track off Nevermind, but the Rock in Rio lineup had Foo Fighters playing right after Weezer, which made this particular performance feel a little more like an explicit tribute. “We’re going to cover a song from Dave Grohl’s old band to tide you over until the main course in a few minutes,” Rivers Cuomo told the crowd before launching into the Nirvana tune.
Grohl later shared his appreciation. “I was backstage and I heard Weezer play the ‘Lithium’ song and I’ve got to be honest, I cried a little bit. I did! I was like [mimics crying]. I miss playing that song,” he told the crowd before dedicating “Big Me” to the band. “So this one goes out to the sweet Weezer.”
He also hinted that a new Foo Fighters album is on its way: “We go home next week and we start making a new Foo Fighters record. It’s good, it’s good.”
Foo Fighters’ last full-length album was 2017’s Concrete and Gold. In anticipation of their debut album’s 25th anniversary next year, they’ve been releasing a series of numbered EPs with rarities, B-sides, and live tracks; their latest, 01070725, included a cover of Arcade Fire‘s “Keep the Car Running.”
