Missing Foundation Is an industrial music and performance art project active in the late 1980s - present and led by Peter Missing. Their live shows were notorious for sparking civil disobedience (including the occasional riot) and causing serious damage to venues at which they performed. The group was also infamous for their "The Party's Over" graffito of an upside-down martini glass, and was heavily involved in the Tompkins Square Park Riot in August 1988. While the band continued to produce music and concerts; a small anarchist social movement continued to exist under the same name for several years .
