Billie Eilish had some special guests at her show last night at Inglewood’s Kia Forum. As Pitchfork points out, Eilish was joined onstage by Foo Fighters‘ Dave Grohl for a duet of their classic “My Hero,” followed soon by a visit from Phoebe Bridgers and her track “Motion Sickness,” which Eilish happily joined.

Just before Grohl’s acoustic performance, he thanked Eilish for her Grammys tribute to Taylor Hawkins, the Foo Fighters drummer who passed away this year. “Earlier this year, all of the Foo Fighters and our families gathered together at my house to watch the Grammys,” Grohl said. “And when Billie came out for her performance in the Taylor Hawkins T-shirt, the room was filled with real tears of love and gratitude. So, from our families who are here tonight, the Hawkins family, and everyone, we’d like to thank you very much for that.”

As nice as the “My Hero” performance is, it’s pretty wild to see Bridgers perform her career-making Stranger In The Alps track in front of tens of thousands of people. The audience is not only appreciative but eager to sing along when they know the words, and Eilish’s backup vocals only add to the momentous feeling. It’s a long way from a FADER cover, that’s for sure.
