FireAid had some surprises in store, but none bigger than the first reunion from Nirvana's surviving members in over a decade.

Surviving Nirvana members Dave Grohl and Krist Novoselic and former touring guitarist Pat Smear reunited at the California wildfires benefit concert FireAid on Thursday night. They played four Nirvana classics with the help of some guest vocalists.

A trio of singers filled in for Kurt Cobain as Dave Grohl, Pat Smear and Krist Novoselic performed "Breed," "School" and "Territorial Pissings.”

The surviving members of Nirvana surprise-reunited for the first time since 2020, for the FireAid benefit concert. And to fill in for Kurt Cobain, they tapped some of the same women who’ve previously taken his place.

Dave Grohl, Krist Novoselic and Pat Smear performed at the star-studded benefit, alongside Green Day, Billie Eilish, Lady Gaga, Red Hot Chili Peppers and loads of others

A rotating group of women vocalists joined the surviving members of the legendary '90s band for a raucous reunion set.
