Ma Rainey, American singer-songwriter (died 1939)

Gertrude "Ma" Rainey was an American blues singer and influential early-blues recording artist. Dubbed the "Mother of the Blues", she bridged earlier vaudeville and the authentic expression of southern blues, influencing a generation of blues singers. Rainey was known for her powerful vocal abilities, energetic disposition, majestic phrasing, and a "moaning" style of singing. Her qualities are present and most evident in her early recordings "Bo-Weevil Blues" and "Moonshine Blues".
