Dark Star Orchestra keep the indomitable legacy of the Grateful Dead twinkling with their spot-on tribute concerts. They plunder the mother lode of the jam-band progenitors' vast output for Deadheads who miss the real deal or for those unfortunates who never had the chance to witness them live. DSO's MO is to replicate momentous Dead set lists from the group's deep archives, and then nail every facet of the music. Clearly, DSO have their inspiration's wonderfully tight/loose chops, fluid sense of time and space, and that all-important stamina to keep on truckin' through the transitive nightfall of diamonds. by Dave Segal
