A history of 1960s activist art group Black Mask. ¿With Up Against the Real, Nadja Millner-Larsen offers the first comprehensive study of the group Black Mask and its acrimonious relationship to the New York art world of the 1960s. Cited as pioneers of now-common protest aesthetics, the group¿s members employed incendiary modes of direct action against racism, colonialism, and the museum system. They shut down the Museum of Modern Art, fired blanks during a poetry reading, stormed the Pentagon in an antiwar protest, sprayed cow¿s blood at the secretary of state, and dumped garbage into the fountain at Lincoln Center. Black Mask published a Dadaist broadside until 1968, when it changed its name to Up Against the Wall Motherfucker (after line in a poem by Amiri Baraka) and came to classify itself as ¿a street gang with analysis.¿ American activist Abbie Hoffman described the group as ¿the middle-class nightmare . . . an anti-media phenomenon simply because their name could not be printed
