Check out the documentary Searching for Sugar Man. It’s an incredible story about Rodriguez, a singer / songwriter from Detroit that despite being incredibly talented never had any measure of success in the US. However, in Cape Town South Africa he was literally more popular than Elvis. What’s interesting is that EVERYONE in Cape Town not only knew about Rodriguez but, as the story in Cape Town goes (and there were many versions), they believed he tragically committed suicide on stage.
The documentary chronicles the search for what happened to Rodriguez and the man they discovered.
