All of the responses so far have been female pop singers. I'd add the following jazz and classical singers as well: Jazz: Bessie Smith; Ma Rainey; Billie Holiday; Ella Fitzgerald; Carmen McRae; Sarah Vaughn; Ernestine Anderson; and Betty Carter. Classical/opera: Eleanor Schumann-Heinck; Kirstin Flagstad; Maria Callas; Hildegard Behrens; Grace Bumbry; Montserrat Caballe; Leontyne Price; Renata Scotto; Joan Sutherland; and Kiri Te Kanawa.
