REBROADCAST: The late musician, Nina Simone, wanted to stay outside any conventional category. Her classical piano training backed up her identity as a songwriter, jazz singer, a blues singer, pop singer and a soul singer. She was “misunderstood,” as one of her famous recordings revealed. Writer NADINE COHODAS helps us to understand Simone’s difficult life in her new biography, Princess Noire: The Tumultuous Reign of Nina Simone. Cohodas has written several books, including a biography of Dinah Washington and the story behind Chess Records.
