Soul of a Man (song) (The) Soul of a Man is a gospel blues song recorded by Blind Willie Johnson in 1930. As with most of Johnson's songs, it deals with a spiritual theme within a blues musical framework. Accompanying Johnson (vocal and guitar) is Willie B. Harris, sometimes identified as his first wife, who sang harmony on the refrain:
The Blues are the essence of the African American laborer, whose spirit is wed to these songs, reflecting his inner soul to all who will listen. Rhythm and Blues, is the cornerstone of all forms of African American music.
