Mark discusses his performance art in this promotional clip for a segment on Art21 Season Four. Art21 included this description of his work: Mark Bradford uses signage and advertisements scavenged from the street to create wall-sized collages which respond to the impromptu networks that emerge within a city, such as underground economies, immigrant communities, or the use of abandoned public space. In his films, Bradford captures and documents the cultural, political and racial conditions of an urban environment.
