Viola Lee Blues (why it has that name no one knows), a wonderful harp riff by Noah Lewis, is short, simple, and to the point.
What a gorgeous, mournful, lonesome tone this guy got out of his small spittletrap. He's subtle, paints the tones by bending notes, shadings of an artist.
He also sings the song, which he wrote, with Gus Cannon's Jug Stompers. Cannon plays banjo, jug, and kazoo. The guitar player in this song was Hosea Woods, but I'm not certain that's him in this 1928 picture.
