From the Bronx, through Europe and the Israeli-Palestinian conflict zone, to the poor neighborhoods of Dakar, you can hear hip-hop sounds on different voices and, surprisingly, with very different social messages. Most of the protagonists in this documentary are very young versifiers and hip-hop singers who pay attention to the speech they deliver, are extremely articulate and very confident in their music and messages, that for them are more effective than any form of open conflict. Not only a very successful music documentary, but also a very solid social document about a whole generation.
