There are a lot of cover bands around and a lot of those are Grateful Dead cover bands. You've seen them, they're good. Most include the music of Jerry Garcia, Bobby Weir et al with other cover songs and some originals mixed in. DSO is a different breed of "Dead" band. What Dark Star Orchestra does is recreate the Grateful Dead. Not with hippie wigs and fake beards but through the live music. They play the setlist song for song in the same arrangements used by the Dead members of that period.
