Space and light, right on the dot for new gallery exhibits

With their gestural brushstrokes atop grids of colored dots, Carol Brown Goldberg's recent paintings are sort of a marriage of abstract expressionism and op art. But that hardly explains the appeal of these captivating canvases, which are precisely rendered and grandly romantic. The large paintings have a sense of depth that evokes the vastness of space, and glistening surfaces that result from the prolific Washington artist's incorporation of pulverized glass.
