Saluting the holiday (Halloween), Sing Out presents a very special live performance by Wake the Dead. The unique all-star band blends Grateful Dead songs with fine Celtic fare, jigs and reels, with fiddles, harp, bagpipes, and great singing. WTD offers a preview of its Halloween show (Sat., Oct. 31) at the new Freight and Salvage, which means the band may play such date-appropriate songs as “Friend of the Devil.”
