DETROIT, MICHIGAN.- A museum survey examining the phenomenon of destruction in art backfired at the event's opening when audience enthusiasm overwhelmed the exhibit. kaBOOM! began its two month run at Detroit's Museum of New Art (MONA) last Saturday and by night's end it was all over, literally. "They even destroyed the pedestals and wall shelves," one museum staffer shrugged in disbelief.  Fires were set in isolated galleries and a wrecking ball for one display had been removed from its chain and used instead as a bowling ball, taking out an installation as well as the corner of one wall. "In a twisted way, it was a wild success," MONA's director Jef Bourgeau says the morning after, on a surprisingly bright note as he wades through the carnage and debris. "At first we were all startled at the extent of the audience's unrestrained joy, at smashing and stomping an entire exhibition to bits. kaBOOM! goes kaput in one night, we were telling each other. The show's over.  What now?"  Bourgeau pauses to gingerly pick up some burned photographs of Marcel Duchamp disguised as Rrose Selavy. He drops them where he found them. They are unsalvageable, a few charred remnants dripping with the urine that was used to douse their flames. "You have to give them credit for being creative. The challenge now," he adds excitedly, "is to pick up the pieces and somehow turn all this back into art. Luckily we have two months left in the schedule to do just that."
