Kase2 (also known as King Kase2 and Case2; born Jeff Brown in New York City, 1958) was a graffiti writer and a significant contributor to the hip-hop movement. He painted his first handball court in 1973 and by 1976 he had painted over fifty major pieces on subway trains in New York City. In the 1980s he popularized his "computer rock" style, a form of wildstyle where letters are broken into boxes and scrambled.
