The band also brought out Dave Grohl's 18-year-old daughter, Violet Grohl, to wrap up the set with an emotional rendition of "All Apologies"

Then came what was perhaps the biggest surprise: Violet Grohl, Dave’s 18-year-old daughter, singing lead vocals on Nirvana’s In Utero highlight “All Apologies.” Her vocals were strong and well-suited for the song, and while the magnitude of the Kia Forum’s crowd wasn’t lost on her, she was remarkably comfortable in front of the massive crowd.

The surviving members of Nirvana reunited at FireAid with guest vocalists St. Vincent, Kim Gordon, Joan Jett and Violet Grohl.
