Saw a show by a GD tribute band called the dark star orchestra. They play note for note reproductions of various dead shows. Not a Deadhead, but it was a really nice show and they drew about 12-1500 folks.
Saw Steely Dan last Summer and was blown away by the musicianship and the sound. Seeing them again next month although I'm a bit wary in that they're playing outdoor venues and the hall isn't likely to match the quality of the Wang Center in Boston.
Regina Carter, a terrific jazz musician, also have a great performance and is well worth catching.
