US stars Billie Eilish, Lady Gaga, Pink and Katy Perry will also perform.
The “one night only” event, called FireAid, will take place at the Intuit Dome and the adjacent Kia Forum in Los Angeles on January 30, as well as being broadcast and streamed live.
FireAid lineup revealed so far
The line-up also features Fleetwood Mac star Stevie Nicks and 10-time Grammy winner Joni Mitchell, Gwen Stefani, the Red Hot Chili Peppers, Gracie Abrams, Green Day, Jelly Roll, Earth, Wind & Fire, Lil Baby, Stephen Stills and Tate McRae.
Two-time Oscar-winning musician Eilish will perform with her brother Finneas O’Connell, while the concert will also mark the first time Dave Matthews and John Mayer will perform live together.
Sir Rod Stewart to perform at LA wildfires support event
Sir Rod, who returned from his home in Los Angeles to the UK permanently after three decades in 2023, will also perform after celebrating his 80th birthday earlier this month.
The concert will “raise money for rebuilding communities devastated by wildfires and supporting efforts to prevent future fire disasters throughout Southern California”, organisers said.
How to watch FireAid and get tickets
FireAid will be broadcast and live-streamed on many platforms, including Apple Music and the Apple TV app, Netflix, Paramount+ and Prime Video.
Tickets for both concerts will go on sale from Wednesday on Ticketmaster and more artists will be announced at a later date, organisers added.
The announcement comes after pop superstar Taylor Swift described the wildfires as “heartbreaking to see”.
The 35-year-old made the comments as she posted a list of organisations she has donated to, including the California Community Foundation Fund, Los Angeles Fire Department Foundation and Los Angeles Regional Foodbank.
“The fires in California have devastated so many families and it has been heartbreaking to see these stories unfold,” the singer wrote on her Instagram story.
“So much suffering, loss and destruction, as many people embark on some of the most challenging times of their lives.
“There are also many amazing organisations and groups banding together to help these communities rebuild.”
Other stars who have donated to the relief efforts in LA included Oscar-winning actors Leonardo Di Caprio and Jamie Lee Curtis, who both pledged one million dollars (£819,000), alongside Desperate Housewives star Eva Longoria.
US superstar Beyonce also confirmed her BeyGood foundation donated 2.5 million dollars (£2.05 million) to the relief efforts, after postponing an announcement which fans speculate will be a tour or a new album.
Other stars who lost their homes to the fires include Paris Hilton, Mel Gibson, Miles Teller, Jeff Bridges, Billy Crystal, Jamie Chung and Bryan Greenberg.
