Best approached with as little foreknowledge as possible, this fascinating, heartwarming documentary tells the story of two South African fans who set out to uncover the truth about '70s folk musician Sixto Rodriguez. While the nature of the source material dictates the quality of the AVC 1.78:1 1080p encode, the DTS-HD MA 5.1 mix excels with its treatment of Rodriguez's music. An audio commentary, 31-min Making of… and theatrical trailer make up the Blu-ray's platter's worthwhile extras.
