In the early '60s, David Grisman and Jerry Garcia were two bluegrass enthusiasts in their early twenties who met after they had seen each other perform. Garcia went on to lead the legendary psychedelic band the Grateful Dead, while Grisman became a world-class mandolin player who blended jazz and bluegrass into a unique style he liked to call "Dawg Music." David and Jerry never lost their enthusiasm for roots music, and in 1973 they formed a progressive bluegrass group called Old and in the Way with Peter Rowan and Vassar Clements. The group quickly gained a large following and sparked a new interest in acoustic music among rock fans, but a falling out led to their breakup after less than a year, and Grisman and Garcia didn't talk for nearly 20 years. In 1991, the pair began working together again, and resumed a fruitful collaboration that resulted in a number of new albums until Garcia's death in 1995. Grateful Dawg, directed by David's daughter Gillian Grisman, is a documentary that looks at the friendship and musical partnership between Grisman and Garcia, and includes live footage of the pair in performance, as well as interviews with a number of their friends, associates, and collaborators.
