What do biker gangs in Tokyo and tombstones in a South African township have in common? According to Roger Gastman and Caleb Neelon, they are both part of a rising subculture of global urbanites who create art and entertainment using their surroundings. Because young people travel and bring their customs and fascinations across borders, this culture becomes a global phenomenon. In Street World, a collection of over 500 photographs taken by amateurs and professionals on five different continents, the editors display bold, full-page images of street culture’s various façades in chapters divided by theme — skateboarding, hip-hop, fashion, graffiti, and transportation. Diamond-studded teeth, kids hanging out in the streets of New York, and colorful shots of people all over the world standing in their closets are also considered part of the movement.
