Question:
Nina Simone (; born Eunice Kathleen Waymon; February 21, 1933 - April 21, 2003) was an American singer, songwriter, pianist, arranger, and activist in the Civil Rights Movement. Simone employed a broad range of musical styles including classical, jazz, blues, folk, R&B, gospel, and pop. Born in North Carolina, the sixth child of a preacher, Waymon aspired to be a concert pianist.
Simone was known for her temper and frequent outbursts. Simone abandoned her daughter Lisa Simone Kelly for years in Mount Vernon after relocating to Liberia. When they reunited in West Africa, Simone became abusive. "She went from being my comfort to the monster in my life. Now she was the person doing the beating, and she was beating me." The abuse became so unbearable that Kelly became suicidal and moved back to New York to stay with her father, Andrew Stroud. In 1985, she fired a gun at a record company executive, whom she accused of stealing royalties. Simone said she "tried to kill him" but "missed". In 1995, she shot and wounded her neighbor's son with an air gun after the boy's laughter disturbed her concentration. According to a biographer, Simone took medication for a condition from the mid-1960s on. All this was only known to a small group of intimates, and kept out of public view for many years, until the biography Break Down and Let It All Out written by Sylvia Hampton and David Nathan revealed this in 2004, after her death. Singer-songwriter Janis Ian, a one-time friend of Simone's, related in her own autobiography, Society's Child: My Autobiography, two instances to illustrate Simone's volatility: one incident in which she forced a shoe store cashier, at gunpoint, to take back a pair of sandals she'd already worn; and another in which Simone demanded a royalty payment from Ian herself as an exchange for having recorded one of Ian's songs, and then ripped a pay telephone out of its wall when she was refused.
