Matthews had been set to take the stage at the Jan. 30 benefit concert in the wake of the devastating Los Angeles wildfires.

CNN has reached out to a representative for Matthews for comment. The FireAid benefit concert, a music event set up to aid the relief efforts following the deadly and devastating Los Angeles wildfires, is set to take place on Thursday at the Kia Forum and the new Intuit Dome, both located in the LA city of Inglewood.

Matthews was scheduled to perform alongside John Mayer for the first time at FireAid, which will be held at the Kia Forum on Thursday.

The sudden cancellation was announced in a brief statement shared on the official Dave Matthews Band Instagram page on Wednesday, Jan. 29, just one day before he was due to take the stage at the Kia Forum with John Mayer for the star-studded FireAid benefit concert raising funds for Los Angeles-area wildfire relief.

Dave Matthews has been forced to withdraw from the LA benefit concert hours before the show starts due to a ‘critical illness in the family’. The Crash Into Me singer was set to perform in a duet with John Mayer at FireAid tonight (January 30) along with sets from Lady Gaga , Billie Eilish , Stevie Nicks and Sir Rod Stewart.
