Gov’t Mule drummer Matt Abts will not perform at this weekend’s Christmas Jam in Asheville, NC due to a family emergency.

Abts will not be able to make it to the show but the band will play on with special guest drummers including Duane Trucks, Paul Riddle and Rock Lindsley, morphing the set into something that resembles “Gov’t Mule & Friends,” which will close out the show on Saturday night.

Christmas Jam will commence tomorrow night with additional performances from Bob Weir, Jamey Johnson, Michael McDonald and more.
