Lady Be Good reveals the lost stories of female jazz musicians from the early 1920s to the 1970s. Narrated by musician-composer Patrice Rushen, the film charts the influence of female players from the struggles and successes of early innovators (Sweet Emma Barrett, Lil Hardin-Armstrong), through the rise of the all-woman big bands (Ina Ray Hutton & Her Melodears, the Hollywood Redheads), to the female musicians that were instrumental players (Dorothy Donegan, Mary Osborne) and arrangers (Mary Lou Williams, Melba Liston) for more famous male band leaders, including Benny Goodman and Quincy Jones. Unfolding over nine parts, director Kay D. Ray's debut film weaves provocative and often humorous interviews with female musicians, big band leaders, jazz authors, and historians throughout a film stuffed end-to-end with archival photos, recordings, and performance footage to create a documentary that restores an essential part of our musical history.
