The latest (but by no means final) roster of additional Jammys performers has been announced. Solomon Burke, Edie Brickell, James Carter and the Derek Trucks Band will all perform on March 16 at the Theatre at Madison Square Garden. Also, as tickets continue to move (with general admission sold out) some additional seats have been released for the show at the rear of the Theatre at a discounted rate. Jammys Tickets can be purchased on line or with no service charges at either the MSG or Radio City Music Hall box office.
