Tuesday, Feb. 17; Stella Blue (21 and over, 9 p.m.): In the spirit of not letting dead Garcias lie, the Dark Star Orchestra tour the country presenting excruciatingly detailed reenactments of Grateful Dead shows, set list for set list, song for song, concert for concert. Going far beyond the realm of most "tribute" bands, the Dark Star Orchestra recreate specific Dead shows given on specific dates, which they keep secret until the encore of each show. They even go so far as to present the shows using replicas of the instruments the Dead used for the original performances. The audience, some of whom may have seen the Dead show to be played out once again, can get clues as to the date of the original show by checking mic number and placement, keyboard setup, guitar and bass varieties, etc., assuming that attending Grateful Dead shows has been their life's work. A Dark Star Orchestra show is just like being dead all over again.
