Rodriguez is unique and his life story is an amazing one. Disappearing into obscurity for a long time, he never received the accolades that his contemporaries did - e.g. Bob Dylan, Neil Young, et al. At least not until he was rediscovered, and even today many have not heard of him. He is one of the greatest, and learning from the film about the type of person he is and how he lives his life only adds to his reputation. As for 'Searching for Sugarman' the album, when was the last time you bought an album with lyrics worth listening to that are political, thought provoking, emotional and more?
Buy an original version, for all the Rodriguez records never sold, concert halls never filled, etc. back in the 1970s, 1980s and 1990s, when he was denied the global recognition he has always richly deserved.
