Alongside Willie Mae Ford Smith, Sister Rosetta Tharpe is widely acclaimed among the greatest Sanctified gospel singers of her generation; a flamboyant performer whose music often flirted with the blues and swing, she was also one of the most controversial talents of her day, shocking purists with her leap into the secular market -- by playing nightclubs and theatres, she not only pushed spiritual music into the mainstream, but in the process also helped pioneer the rise of pop-gospel. Tharpe was born March 20, 1921 in Cotton Plant, Arkansas; the daughter of Katie Bell Nubin, a traveling missionary and shouter in the classic gospel tradition known throughout the circuit as "Mother Bell," she was a prodigy, mastering the guitar by the age of six.
