One of the oldest staples of the American jam-music scene, Athens, Ga., rockers Widespread Panic have been playing together since the mid-'80s, well before the jam scene was the organized network it is today.

Last spring the group released its 11th studio album, the Southern-rock-oriented set Dirty Side Down. (Through Oct. 22)
