There is no way around this fact: American cinema was founded by a deeply racist film, D.W. Griffith’s The Birth of a Nation, which, as everyone knows, or should know, was originally called The Clansmen. The film, which pictures the KKK as heroic, and black American males as stupid and obsessed with white women, premiered in 1915 and did well at the box office. Almost 100 years later, the turntable wizard, producer, editor, and philosopher Paul D. Miller, aka DJ Spooky, made a remix of this work that scrambles its racist imagery and codes. With this remix/experiment, the recombinatory aesthetics of hiphop, a black American form, are expanded to the art of moving pictures.
