Dan Steinhilber is a goofball artist who makes goofball art. He’s one of the last in D.C. you might expect to pick up the backing of the stately Kreeger Museum, a modernist collection tucked away in a Philip Johnson-designed residence in tony Foxhall. It is, of course, a perfect match: Steinhilber’s work isn’t made for the politically nuanced, aesthetically rigged “white cube” layout that dominates contemporary art galleries. At his last show for G Fine Art, he spent several weeks chopping up plastic bags with an electric lawnmower and ironing the carnage into something like paintings. The Kreeger is exactly the sort of venue Steinhilber was born to disrupt; or rather, he’s precisely the kind of artist to give the museum some life.
