Dave Matthews passed on the FireAid benefit concert Thursday.

“Due to a critical illness in the family, Dave Matthews is unfortunately unable to perform at the FireAid and MusiCares benefits this week,” the Dave Matthews Band posted on its Instagram page read.

CNN reported that Matthews and John Mayer were supposed to play live together for the first time at FireAid, and Mayer responded to the news with a message of his own.

“Sending all my love to Dave, who will be there in spirit with me at (FireAid)” Mayer wrote on his Instagram story.

The benefits are set to aid relief in the wake of the fires in Los Angeles.

A 501(c)(3) was set up, and contributions to FireAid will be distributed under the Annenberg Foundation, which with FireAid has assembled a small committee to advise.

On Friday, Matthews was slated to perform at MusiCares’ 2025 Persons of the Year benefit gala honoring the Grateful Dead.
