Incredible live performance from Nina Simone. Wonder where it was shot? Video is tagged as Harlem, 1969. Hat tip to Wax Poetics.
If you want more of Miss Simone live, check out the DVD Nina Simone Live at Montreaux, 1976. It's a great show - she'd been away from performing for a number of years, living in Africa. She walks out onstage, the crowd duly applaud, and she stands there glaring at them, as if to say "Yes, it's me. Clap harder". Bonus footage includes some of her 1987 and 1990 performances at Montreaux.
