Bayou Maharajah explores the life and music of New Orleans piano legend James Booker, the man Dr. John described as "the best black, gay, one-eyed junkie piano genius New Orleans has ever produced." A brilliant pianist, his eccentricities and showmanship belied a life of struggle, prejudice, and isolation. Illustrated with never-before-seen concert footage, rare personal photos and exclusive interviews, the film paints a portrait of this overlooked genius.
