Last weekend i saw this documentary on one of the favelas of Rio de Janeiro, Brazil and how the corrupt police and drug dealers were taking over and causing violence and killings. The documentary is about one man who decides to turn the situation around and with the help of music, start a social project in the slums. It is very inspirational documentary and shows that all it takes is a few guys, an idea and a strong belief in the idea to improve the situation. And look out for the good metaphore at the end! The website of the documentary is http://www.favelarising.com/ and maybe you can also find it in youtube or google videos...otherwise just buy it! :) Enjoy!
