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

St. Vincent, Joan Jett and Kim Gordon joined Pat Smear and original Nirvana members Dave Grohl and Krist Novoselic onstage for a reunion of sorts at FireAid Thursday. Violet, Jett, and Gordon each subbed in for the late Kurt Cobain.

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

Legendary grunge band Nirvana reunited at Fireaid for a benefit concert on Thursday, January 30, to support the LA wildfire relief effort.

The significance of the opening in Ireland is that Cobain had Irish roots himself, having ancestors who emigrated to the United States from Carrickmore, County Tyrone, in 1875. Cobain was even due to perform with Nirvana at Dublin’s RDS Arena a mere three days after he killed himself in April 1994.

Nirvana's surviving members made a brief unannounced and unexpected reunion during FireAid, a charity concert raising money for those affected by the LA wildfires. Dave Grohl, Krist Novoselic, and Pat Smear reunited to perform four tracks during a short set in Inglewood on Thursday (January 30) night.

Meanwhie, a whole host of other performances came from stars including Lady Gaga and Stevie Wonder. Green Day and Billie Eilish performed the rock band’s hit Last Night on Earth together, while Joni Mitchell took to the stage aged 81 for a rare performance.

The surviving members of Nirvana — drummer Dave Grohl and bassist Krist Novoselic, as well as touring guitarist Pat Smear — reunited for the first time in five years at the FireAid benefit concert.
