Black Flag were the pioneers of American Hardcore and this is their blood-spattered story. Formed in Hermosa Beach, California in 1978, for eight brutal years they made and played brilliant, ugly no-holds-barred music on a self-appointed touring circuit of America's clubs, squats and community halls. Spray Paint The Walls tells Black Flag's story from the inside, drawing on exclusive interviews with the group's members, their contemporaries and the bands they inspired.
