Grateful Dawg is a romanticized remembrance of the collaboration between two musical luminaries, Jerry Garcia and David Grisman -- and its overly fond tone shouldn't be surprising, since it's directed by Grisman's daughter, Gillian, which makes it something less than a complete examination of these men's lives. For example, mention is not even made of Garcia's famously dominating drug life and what effect it had on their work, except for general references to the loose nature of rehearsal sessions, to accommodate the Grateful Dead front man. But given the large percentage of footage devoted to Garcia and Grisman hunched over instruments, plucking sweet music from their strings, it's doubtful that Gillian Grisman intended to contribute to the world of probing documentaries. As a concert film interspersed with interviews, Grateful Dawg is quite a listen. Deadheads won't be interested by the generic platitudes of interview subjects, anyway -- they'll find the most substance hearing Garcia's frail warble accompany bluegrass and other musical forms that were very experimental for him, late in his career. Gillian Grisman made the film after Garcia's death, but by drawing from old radio interviews, she keeps him a clear voice in the film. She has also gathered some priceless photos of the two before they were famous longhairs, suited and clean-cut, playing such "square" instruments as the violin.
