The Rat Bastard Protective Association was an inflammatory, close-knit community of artists who lived and worked in a building they dubbed Painterland in the Fillmore neighborhood of midcentury San Francisco. The artists who counted themselves among the Rat Bastards—which included Joan Brown, Bruce Conner, Jay DeFeo, Wally Hedrick, Michael McClure, and Manuel Neri—exhibited a unique fusion of radicalism, provocation, and community. Geographically isolated from a viable art market and refusing to conform to institutional expectations, they animated broader social and artistic discussions through their work and became a transformative part of American culture over time. Anastasia Aukeman presents new and little-known archival material in this authorized account of these artists and their circle, a colorful cultural milieu that intersected with the broader Beat scene.
