Fergus McCaffrey’s elegant booth mingles the practices of two American artists who came of age in the 1960s and happen to be great friends. The works of Marcia Hafif and Richard Nonas, however, differ greatly—and that’s precisely what makes this presentation so compelling. Hafif’s hyper-saturated canvases featuring curvaceous forms that resemble bodily contours (she calls these her “Pop-Minimal” paintings) draw you in. Nonas’s more subtle patinaed steel sculptures cover the floor. They resemble architectural forms or ritualized objects; given Nonas’s early years as an anthropologist, they just might be inspired by them, too.
