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.

Dave Matthews will be sitting out the FireAid and MusiCares benefit concerts due to a 'critical illness in the family.'

Dave Matthews will no longer perform at FireAid, the star-studded benefit concert organized for Los Angeles-area wildfire relief taking place Thursday.
