Howard Barlow's last sculptures were made of bright orange earplugs and cubes of metal, painted in cheerful colors and riddled with bullet holes. For his new works (including Seven Pains Mended and Big Guns Make Good Neighbors) the Thorp-based artist uses institutional powder-coat colors, gun-barrel patina finishes, recycled bullet-lead solder, broken window panes, wool yarn, and abused steel—all of it knitted, hacked, shot, and shattered.
