WATCH: Nirvana's surviving members perform with Joan Jett, Kim Gordon and more for FireAid Benefit

Dave Grohl, Krist Novoselic, and Pat Smear reunited on stage for a surprise Nirvana set at the FireAid benefit concert on January 30 at the Kia Forum in Los Angeles. The trio ran through several Nirvana classics, with guest vocals from St. Vincent, Joan Jett, Kim Gordon, and Violet Grohl.

St. Vincent kicked things off with "Breed", followed by Gordon taking on "School". Jett stepped in for "Territorial Pissings" before Violet closed it out with "All Apologies".

St. Vincent, Jett, and Gordon had previously joined the surviving members of Nirvana for the band's 2014 Rock and Roll Hall of Fame induction.
