Even if you didn’t know that Trevor Young and Elizabeth Mandeville were married, it would be easy to detect a resonance between their paintings: Though Young prefers urban scenes and Mandeville rural settings, both have a habit of reducing broad sweeps of walls, fields, and sky into hazy, abstract planes in the tradition of Richard Diebenkorn. For the Troyer Gallery’s five-artist show, “Young Painters,” Young continues his impressive string of canvases for the gallery, this time supplementing his traditional gunmetal-gray palette with softer hues, such as peach and pink, as well as more organic tones, such as the dark brown that envelops the one lit window in NOAA Intimate. In the ultraglossy oil-on-canvas Green Resting in Yellow, Young even delves into pure abstraction, something that Mandeville also flirts with in her creamy paint-and-newsprint collage, Stonewashed. Elizabeth Roberts, another repeat Troyer exhibitee, offers new color variations on her signature textile-inspired crosshatch paintings—this time, in a nice conceptual trick, executing some of them on pieces of fabric. Tom Costa paints vertical, brown-hued, imaginary landscapes (You Are Here is pictured), while Katherine Krebs—like Costa, a recent art-school grad—uses such materials as oil, acrylic, gouache, and epoxy to experiment with various scales and degrees of abstraction. Unlike Young, Krebs hasn’t yet established an identifiable style; she ranges from Island’s surreal War of the Worlds imagery to more intimate, agatelike color abstraction of Living Room Window I and II. But as the show’s title notes, she still has time to develop one. The exhibition is on view from 11 a.m. to 5 p.m. Tuesday to Saturday, to Saturday, Sept. 28, at the Troyer Gallery, 1710 Connecticut Ave. NW. Free. (202) 328-7189. (Louis Jacobson)
