An incredibly candid documentary on the late high priestess of rock, Janis Joplin. The film captures all of the brilliance of her wailing, mesmerizing on-stage performances, but it is not just a performance film. The filmmakers seem to have known Janis intimately, and have captured her fragile, girlish personality in some rare off-stage interviews. The film features most of Janis' musical repertory, including the classic "Kozmic Blues", and "Me and Bobby McGee", her last hit.
