For thirty years graffiti artist Risk has written on the streets of Los Angeles. Curating for MOCAtv, he shares a BBC documentary from the 1989 international street art competition in Bridlington, UK, where he and co-conspirator Slick represented the United States and were recognized for the electric, interlocking alphabet letters that Angelenos would come to find on busses, corners, and highway overpasses. “Los Angeles is a tough city,” his younger self says. “Graffiti is a form of rebellion and passion.” Watch out for the menacing taggers, whose arrival augurs an acid house-era update of the bank holiday face-off between mods and rockers in Quadrophenia.
