The shelf-like wall sculptures on view in this show are perhaps a bit more conventional in terms of materials -- all are made of gaudy-colored cast rubber -- but the overall effect is as far-out as ever. The pieces look like they are in the process of morphing from shelves into living organisms. They may constitute an ode to Minimalism, but Donald Judd they are not. Long's writhing snake and vine-like forms, which seem to grow out of the shelves, and writhe and slither along the walls, belong to neither plant nor animal kingdoms. They, like many of Long's works, are in a category all their own.
