There's a current artsy-fartsy movie out about Sixto Rodriguez. He released an album in '71 that royally flopped here in the US but by chance caught fire and sold scads of copies in So. Africa. After that he disappeared from the scene. The movie, something like "Searching for the Sugar Man", chronicles the search of a guy in So. Africa to find out what happened to Rodriguez. Great movie and very moving story.
You can google "Rodriguez Cold Fact" for info, audio, and video.
