Director Doug Pray (Hype) pays tribute to the innovative art of DJing in the electrifying documentary "Scratch." Featuring the most legendary figures in the DJ scene, Pray's film is at once a deeply insightful historical document and a highly entertaining glimpse into the world of underground hip-hop. Modern luminaries such as DJ Shadow, Mix Master Mike (of the Beastie Boys), DJ Qbert, Rob Swift, and DJ Swamp are interviewed alongside living legends like Afrika Bambaataa, Jazzy Jay, and Grand Mixer DXT, in order to paint a broad, comprehensive picture of how DJing has evolved over the years.
