Dave Matthews and former Berklee School of Music student John Mayer will perform live together for the first time at FireAid.

Relief efforts for the still-burning fires in California have now reached the “massive benefit concert by very famous people” stage of developments, as organizers for an upcoming event titled FireAid have now sent out their initial line-up for a benefit concert.

Dozens of artists, many of whom have ties to Los Angeles, are lending their talents to wildfire relief. Billie Eilish, Lady Gaga, Joni Mitchell, Stevie Nicks, Katy Perry, and the Red Hot Chili Peppers are among those performing at the benefit concert FireAid.
