SCRATCH is a feature-length documentary film that explores the world of the hip-hop DJ. From the birth of hip-hop, when pioneering DJ's began extending breaks on their party records (which helped inspire break dancing and rap), to the invention of scratching and "beat-juggling" vinyl, to its recent explosion as a musical movement called "turntablism," it's a story of unknown underdogs and serious virtuosos who are radically changing the way we hear, play and create music.
