RISK (born Kelly Graval), also known as RISKY, is a Los Angeles-based graffiti artist and fashion entrepreneur. In the 1980s, RISK gained notoriety for his unique style and pushed the limits of graffiti: He was one of the first writers in Southern California to paint freight trains, and he pioneered writing on "heavens", or freeway overpasses. At the peak of his career he took graffiti from the streets and into the gallery with the launch of the Third Rail series of art shows, and later parlayed the name into a line of graffiti-inspired clothing.
