On their own, the crisp, vacant, urban-landscape images by Lauren Henkin would be intriguing enough—spindly tendrils climbing up a warehouse façade that suggests a color-field painting (shown); a tree that curves gracefully skyward from behind a mess of Dumpsters and recycling bins; and rusted barrels in shades of yellow, lavender, and baby blue stacked in an orderly fashion. The images ponder what’s supposed to be there, and what isn’t, sometimes with a less-than-clear resolution. But there’s more. Henkin’s meditation on invasiveness asks how we choose whether to extinguish an outsider or let it be. This question is particularly pressing for Henkin, because it stems from her experience with two major abdominal surgeries; she pairs the landscape images with medical scans of her own fleshy invaders. “I needed to change my perception of what is ‘invasive,’” she writes, “to find some kind of respect for anything that persists in growth, no matter what the environment.” The exhibit is on view Tuesdays to Fridays noon to 5 p.m. and Saturdays 11 a.m. to 5 p.m. at the Gallery at Vivid Solutions, 1241 Good Hope Road SE.
