This movie is a documentary showing the evolution of a musical style. Fortunately for the viewer, it is also an opportunity to see some of the practitioners of that style in much footage never before released. A must-see for devotees of the style, enlightening and entertaining for others. The effective use of interviews, physical tours of the birthplaces of the music and lengthy performances give the viewer quite an overview of this music and its practitioners. An illuminating look at the gutsy and raw Delta-inspired music.
