There's an obvious desire to see how the city has changed over the past year through its art. After all, New York art was always so responsive to social upheaval. From the mid-Eighties, for example, the art community was profoundly affected by Aids and spoke articulately of the crisis. The works of Felix Gonzalez-Torres, charting his slow demise through Aids combined with touching moments of intimacy, for example, have become notable symbols of that responsive moment. By contrast, one of the traditional end-of-season group exhibitions on display at the moment is called Penetration. It's pretty much self-explanatory and hardly profound (although occasionally profoundly hard). These days, it's sex without the politics.
