These organized street works can be understood as extensions of both the Pop art Happenings of the earlier 1960s and the street protests taking place in New York City and throughout the country during the 1968 elections, the Civil Rights Movement, and the Vietnam War. Whereas the Pop happenings usually took place in galleries and performance spaces, the street works were unconfined by physically walled-in spaces. Enacted in open environments, comingled with the natural flow of pedestrians, these performances created unlimited possibilities for happenstance; with the sidewalk as the stage and the city as backdrop, the inhabitants of New York became active participants with the artists, willingly or not.
