(nyt) “I will never be your clown,” Nina Simone shouted at a restless nightclub audience in Cannes in 1977. The mostly French-speaking crowd was either unable or unwilling to join her in a singalong, and she took it as a personal affront. “God gave me this gift — and I am a genius. I worked at my craft for six to 14 hours a day, I studied and learned through practice. I am not here just to entertain you. But how can I be alive when you are so dead?” Her speech only prompted more requests for her to “SING!” She managed to get through some songs before delivering her parting words. “You owe me,” she railed. “I don’t wear a painted smile on my face, like Louis Armstrong.” Scenes like this were all too common, especially during the latter half of Simone’s career. Her reputation as mercurial, moody and combative was well established, and she did little to dispel this image in her memoir, “I Put a Spell on You.” She was nothing if not paradoxical. She promoted black militancy and spoke of her love for “my people,” but often treated black audiences with contempt and condescension. She beat up white audiences, too, sometimes declaring her disdain for white people, and yet sustained a substantial crossover following with covers of songs associated with their youth culture. She might show up an hour or two late, ramble incoherently onstage and suddenly give a performance that could bring a weary crowd to tears.
