Pop stars, first responders, rock stars and those who have lost everything in the devastating Los Angeles-area wildfires came together for FireAid, a massive benefit concert Thursday that combined spectacular performances with moving storytelling from survivors.

In a night full of surprises, a reunion of Nirvana — fronted by St. Vincent, Kim Gordon and Joan Jett in the place of the late Kurt Cobain — tops the list. They launched into “Breed,” “School” and “Territorial Pissings” respectively, inspired and unexpected choices. Drummer Dave Grohl’s daughter, Violet, then emerged onstage for “All Apologies.”

Closer Lady Gaga, after powering through “Shallow” and “Always Remember Us This Way,” played a new song on the piano.

“It’s just for tonight, it’s just for you,” she said of the song she wrote with fiancé Michael Polansky, “Time is a healer.”

Green Day kicked off the massive show by launching into “Last Night on Earth” and was soon joined by Billie Eilish for the first surprise of the night. The lyrics are surprisingly astute: “If I lose everything in the fire/ I’m sending all my love to you.”

After the set, Green Day frontman Billie Joe Armstrong hugged actor Billy Crystal, who welcomed the crowd.

“Our goal is simple tonight, to spend more money than the Dodgers spent on free agents,” Crystal joked.

He told the audience U2 offered the first big donation of the night: $1 million. Crystal said he was wearing the clothes he had on when he evacuated. He lost his home in the Pacific Palisades where he lived for 46 years.

There’s no band more Southern California than the Red Hot Chili Peppers, and bassist Flea did a handstand onstage wearing only a Speedo before they launched into one of their countless odes to the state: “Dani California,” “Californication” and “Under the Bridge.”

The first true-blue Los Angeles moment came from a surprise performance by Dr. Dre. The progenitor of West Coast hip- hop tackled “Still D.R.E.” with Anderson .Paak and Sheila E. before pivoting to Tupac and Dre’s classic “California Love.”

It was followed by the figurehead of Laurel Canyon folk, a moving set of “Both Sides Now” by Joni Mitchell.

Later, Orange Country ska punk legends No Doubt launched into “I’m Just a Girl,” “Don’t Speak” and “Spiderwebs,” led by Gwen Stefani.

Stevie Nicks did “Edge of Seventeen,” “Stand Back” and “Landslide,” and told the story of evacuating her Pacific Palisades home that miraculously did not burn down. Her home is mostly wood, built in 1938, and she theorized its loss would have destroyed the whole street.

Between sets, survivors telling stories of losing their homes were broadcast, both in person and in video packages.
