More than a musical genre, it’s a global phenomenon. Business, sport, fashion, politics – hip hop influences it all. In this four-part series Eve Jackson meets some of the genre’s pioneers in New York including one of the first-ever DJs Grandmaster Flash and the underground fashion designer Dapper Dan who became a Gucci god. She also meets rising star Kenzo B in the Bronx and looks at how France became the second largest rap music market in the world.
