The documentary begins with setting the perspective to several light years. The voyager is traveling our milky-way with the sounds of our earthly lives, as a space monument for (possible?) extraterrestrials.

The documentary contains footage of Willy Dixen, Robert Johnson, Skip James and J.B. Lenoir. The footage of J.B. has never been published before. The narrative is from 'blind Willie' Dixon. However, it's done by an actor. The film shows the work of all these early blues men followed by covers and interpretations by musicians, such as Nick Cave and the bad Seeds among others.

The Death of J.B. Lenoir (John Mayall's song) is a striking event in the story. Lenoir got political engaged and is considered to be of the league of Martin Luther King and peers. His political interests can be found in the themes of his lyrics.

Blues is found to be 'THE' native music of America. Blues is the roots and the rest is the fruits.

The title 'Soul of a Man' is after a Willie Dixon song.
