A stirring profile of soul singer Sharon Jones, often called the female James Brown, as unstoppable in life as she is on stage, as she marshals her volcanic power to battle cancer, break down barriers in the music business, create a new album, and prepare for a world tour. From her early days, when music-industry executives said she was “too black, too fat, too short, and too old” to become a star, through her breakthrough success with the soul-based band the Dap-Kings, to her latest challenges and triumphs, Sharon Jones is as mighty on screen as she is in life. This is the latest documentary from the two-time Academy Award winning Barbara Kopple (Harlan County, USA), who demonstrates the power of cinema vérité as she follows her subject for over a year.
