As one could well expect, the additions to the Warren Haynes Christmas Jam continue. John Popper is now on board joining fellow guest musicians Audley Freed, Col. Bruce Hampton, Jorma Kaukonen, Kevn Kinney, Edwin McCain, Charlie Musselwhite and Dave Schools along with Gov’t Mule, Galactic, Little Feat, Living Colour and Neville Brothers. Other performers are yet expected to pile on, with the festivities scheduled for the Asheville Civic Center Arena on Saturday, December 18.
