The Buena Vista Social Club is a really good documentary celebrating some of the forgotten heroes of Cuban Music of the time that have since passed, such as Compay Segundo, Rubén González, and Ibrahim Ferrer. If you enjoy music from Cuba or Latin music that documentary is for you. Again another nod to Hulu.com.
