Nina Simone was an American composer concert pianist, singer, songwriter, and civil rights activist. Simone's bearing and stage presence earned her the title the High Priestess of Soul. Her music spanned styles including classical, folk, gospel, blues, jazz, R&B, and pop. Her piano playing was strongly influenced by baroque and classical music, especially Johann Sebastian Bach, and accompanied expressive, jazz-like singing in her contralto voice. Rolling Stone named Simone one of the greatest singers on various lists.
