George Pratt, a creator of many fine graphic novels, takes a journey to the heart of blues country in preparation of a future work. On his travels he meets with a number of individuals who still keep the spirit of the delta blues alive the son of Mississippi John Hurt, and makes a poignant visit to the graveside of this blues legend. Intercut with these personal reminiscences is archival footage of blues legends like Howlin' Wolf and Muddy Waters. While lacking the detail of many other histories of the blues; this one benefits from Pratt's insight into the depth of the culture and the sheer power of the music. Pratt's art as a work in progress is also used to illustrate his creative process, and its inclusion is an interesting addition to the standard documentary.
