Amandla! A Revolution in Four-Part Harmony, was directed by Lee Hirsch, who sold all his possessions and dropped out of college to make the film. That's the level of commitment and passion exhibited by the creators, but it has nothing on the people starring in this documentary, which focuses on the role music and dance played in the downfall of the Apartheid system in South Africa. I cried at the atrocities committed by the government, and nearly danced for joy myself near the end when Nelson Mandela was shown finally released from prison. The most inspiring aspect of the music in this film is that despite the suffering, there isn't a single "sad" song to be found. The soundtrack is unbelievable, featuring performances and interviews by dynamic and influential artists/activists such as Miriam Makeba, Vusi Mahlasela, Abdullah Ibrahim, and Hugh Masekela.
