In joining the muzzles of two cannons—105mm Howitzer replicas—with a tubular element, Blowback thwarts the weapons’ potential to wreak outward violence. Instead, a physical and symbolic link between these opposite forces is created. Such retooling conjoins these typically antagonistic objects into a sort of marriage. Whereas the “blowback” phenomenon typically sees the use of a weapon against its benefactor or innocent civilians, in this work the cannons can only blow back on one another. Here, war is won with amorous sabotage.
