Whether it takes the form of ephemeral graffiti or great frescoes--mural paintings are the ultimate freedom of expression, an ancient craft that reflects all the whispers and cries of our world. From Philadelphia to Johannesburg, from Santiago de Chile to Jerusalem, from Mumbai to Gdansk, the walls of our cities show all the doubts, fears, fights, violence, and hope for a better world with more equality. This photographic project, presented with music from all over the world, testifies to our history and reveals that the concerns of men are similar from one end of our planet to the other.
