The Oscars are on Sunday, and Searching for Sugar Man is up for the Documentary Feature award. Two fans want to find out what happened to an enigmatic singer whose message of peace and love inspired South Africa during its darkest days of apartheid. Their hunt ends in Detroit, where the troubadour has carried on as a serene, soft-spoken construction worker. Though it could have dug a little deeper, Searching for Sugar Man is a rather sweet celebration of the power of music and the magic of life’s surprises. It’s available from Acorn, and can be requested from SWAN.
