For Kermit Berg, an artist based in Berlin and San Francisco, the “vast stretches of fluorescent lighting indoors and neon lighting outdoors in Tokyo have been a powerful influence.” That’s clear from “Tokyo Night Office,” an exhibit at Gallery Plan B featuring works that are clearly photo-based but otherwise leave their multilayered technique obscure. Most of the images are bursting with energy, melding such far-flung imagery as train maps, vending machine contents, advertising, endless walls of office-building windows and simple squiggles of color. But the calmer, less complex images are most appealing—-a blocky arrangement of orange and black with a splotch of green that looks like a police-car light; a dark black space punctuated by blue neon lettering and geometrical green shapes; and one muted work that’s “intentionally dimmed” to honor the victims of this year’s natural and man-made disasters in Japan. Also on view: mixed media works on canvas by Delna Dastur, an artist based in northern Virginia and Mumbai, India, whose abstractions toy with cubism, Islamic art, and decorative themes.

The exhibition is on view 12 to 7 p.m. Wednesday to Saturday and 1 to 5 p.m. Sundy to Nov. 20 at Gallery Plan B, 1530 14th St. NW. (202) 234-2711.
