As part of a presentation entitled “The 15th Spectacle,” the inimitable New York experimental performance artist and filmmaker Stuart Sherman will screen several of his short films and then give a performance. The films I’ve seen tend to evoke Buster Keaton with their deadpan humor and simplicity; they are also philosophical in their implications and undertones. If you haven’t been exposed to Sherman’s work, this evening should provide a welcome introduction; those who already know his take on things don’t need my recommendation.
