First used to describe the work of a group of artists working in San Francisco in the late 1950s, and later used as the title of an exhibition held in Callifornia in 1967. The style is characterized by a preoccupation with sick, shocking, and sexually provocative imagery resulting in bizarre combinations of materials such as leather, steel, clay, vinyl, fur, and ceramics.
