Big Bill Broonzy was an American blues singer, songwriter, and guitarist. His career began in the 1920s, when he played country music to mostly African-American audiences. In the 1930s and 1940s, he navigated a change in style to a more urban blues sound popular with working-class black audiences. In the 1950s, a return to his traditional folk-blues roots made him one of the leading figures of the emerging American folk music revival and an international star. His long and varied career marks him as one of the key figures in the development of blues music in the 20th century.

Blues is a music genre and musical form that originated amongst African-Americans in the Deep South of the United States around the 1860s. Blues incorporated spirituals, work songs, field hollers, shouts, chants, and rhymed simple narrative ballads from the African-American culture. The blues form is ubiquitous in jazz, rhythm and blues, and rock and roll, and is characterized by the call-and-response pattern, the blues scale, and specific chord progressions, of which the twelve-bar blues is the most common. Blue notes, usually thirds, fifths or sevenths flattened in pitch, are also an essential part of the sound. Blues shuffles or walking bass reinforce the trance-like rhythm and form a repetitive effect known as the groove.
