An absolute highlight of FireAid was the comet-like reappearance of the remaining members of Nirvana onstage together playing the band's songs again.

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

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

The surviving members of Nirvana reunited for a surprise performance at the FireAid benefit concert in Los Angeles, California last night (January 30th), with the grunge icons having hit the stage to play a few classic songs alongside guest musicians St. Vincent, Kim Gordon, Joan Jett, and Violet Grohl.

FireAid, a sprawling benefit concert for wildfire relief, featured Joni Mitchell, Stevie Wonder, Billie Eilish, Lady Gaga, members of Nirvana and dozens more.

Dave Grohl, Krist Novoselic and Pat Smear reunited and were helped by variety of guest vocalists for a Nirvana performance at the FireAid benefit concert.

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"

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

Krist Novoselic, Dave Grohl, and Pat Smear—came together last night at FireAid, a benefit concert at the Kia Forum in Los Angeles raising funds for victims of the recent California wildfires.

According to Kim Gordon, women are "natural anarchists" because they are hard-wired to fight from the off, which filters into many musicians' art.
