Dave Matthews drops off FireAid and MusiCares concerts due to ‘critical illness in the family’

Dave Matthews has dropped off the FireAid and MusiCares Person of the Year benefit concerts.

In a statement posted to Facebook, the “Ants Marching” rocker shares he’s dealing with a “critical illness in the family.”

At FireAid, which takes place Thursday and raises money for Los Angeles fire relief efforts, Matthews was set to perform a set alongside John Mayer.

The MusiCares Person of the Year gala will be held Friday in LA and honors the Grateful Dead.
