Kochs’s paintings are constructed as much as they are painted, built up with layers of folded canvas, cardboard, and paper and covered with oil paint, charcoal, and graphite. The resulting surfaces are incredibly tactile, resembling reliefs, and lead the viewer into illusionary space, where subjects bleed into hazy, sometimes abstract fields of line and color.
These painterly grounds serve as the backdrops for a cast of ghostly, almost cartoon-like figures. Koch renders his subjects with a graphic simplicity that blurs facial features and pares bodies down to blocks of color and shape. Sometimes it’s just the faded outline of a person that emerges from the surface, as though the figure has been lifted off an older painting and placed on this new one. The compositions feel more like palimpsests—layers of different times and places—than static, straightforward images.
