The prime challenge for a representational artist working in the contemporary-art arena is to come up with something that looks new. And since artists have been mining realism since the days of the cave painters, that's not so easy to do...which made the handsome and tastefully installed Roots — New Drawings by Heidi Jung a show to remember. Jung zeroed in on the roots and shafts of plants, which she rendered with staggering accuracy in charcoal and ink on architectural vellum. The vellum was laid on birch panels, making frames unnecessary. Jung's drawing style is elegant, with the tangled complexity of the roots and shafts set against the bareness of the surrounding blank vellum in just the right combination. Despite being examples of straightforward realism, depicting dead plants, no less, Jung's drawings somehow looked utterly fresh.
