American gospel musician
According to Wikipedia,
Sister Rosetta Tharpe was an American singer and guitarist. She gained popularity in the 1930s and 1940s with her gospel recordings, characterized by a unique mixture of spiritual lyrics and electric guitar. She was the first great recording star of gospel music, and was among the first gospel musicians to appeal to rhythm and blues and rock and roll audiences, later being referred to as "the original soul sister" and "the Godmother of rock and roll". She influenced early rock-and-roll musicians including Little Richard, Johnny Cash, Carl Perkins, Chuck Berry, Elvis Presley, Jerry Lee Lewis, and Eric Clapton.
