On a school trip in 2014, I went to the Hirshorn Museum in Washington, D.C. At the time, the Hirshhorn had an exhibit on destruction in art. A short film was playing on loop in the gallary, and I haven't been able to find out the title, the creator, or any footage of it online. Someone on wordpress who also didn't know the title of the film describes it as such: "In another continuously running film, a well-heeled man sits in his modern apartment and stares at a tomato. In alternating scenes, a pony-tailed man, a poor artsy type, sits in his messy apartment staring at a chunk of tree bark. The two men meet in a studio and sit in chairs facing each other; a woman in black acts as referee and signals them to begin. They both stare and stare at each other. Suddenly both of their heads explode off their bodies, blood shooting everywhere. Yikes! " Aside from this post and a list of artists at the exhibit, I can't find any information about it online.
(And yes, I've emailed the Hirshhorn about it. They never responded.)
