The painted backgrounds are interesting in that they play down the veneer, whose seamless, bravura technique has always been the salient feature and primary content of Ms. Taylors work. Still, six versions seem more about demand than about artistic development. The shows redemption comes in the final gallery: "Silver Fox" is an elegant, playful riff on wood grain made from various kinds of veneer in tones of brown, gray and silver. They are assembled into an ambiguous image that alternately reads as flat and abstract, and as cavernous and scary (something like a Charles Burchfield); big, noticeably fake facsimiles of wood knots add to the spatial confusion. "Silver Fox" is the first work Ive seen by Ms. Taylor that has not been a Photo Realist painting converted to marquetry and is the best thing she has ever done. "Kelso," a more conventionally trompe loeil work, also has promise. When Ms. Taylor finished these pieces, she would have done well to cancel this show and keep on working, ...
