Listen to these vandals explain what graffiti is, and what it means. hear them describe spray paint cans as "toxic volatile substances" that are "explosive" and "dangerous." And watch them explain why bombing is "the biggest art movement in the history of humankind." So what if it only took over America in the 1970s. This shit is bigger than hieroglyphics! Which is why former music video director Jon Reiss has just released the new doc BOMB IT, touring cities like Los Angeles, New York, Philadelphia, San Francisco, Tijuana, London, Paris, and Amsterdam to see who's pissing off local community boards.
