Many of Lee Kelly's wall sculptures stand away slightly from the wall where they can also seem like immense brushstrokes. But there are “shadow” versions of them, too the spaces just behind them. We can’t, of course, enter that space—the works remain, in this sense, two-dimensional. Yet it is there, and its contradictory “presence” reminds us that the work is because of what it isn’t.
