Unfettered by the demands of the commercial marketplace, the privately supported Art and Culture Center has taken that freedom and run with it, charting a course that sometimes appears to be fearless. Where else, for instance, would you find something as esoteric as "Exploding the Lotus"? That multimedia show displayed the work of nearly two dozen artists from the Indian subcontinent with a strong emphasis on the conceptual. Or how about "Nathan Sawaya: The Art of the Brick," an exhibition of art made exclusively with Lego parts? And we're still scratching our heads over the quirkiness of the recent "TM Sisters: Idealtonight." Under such adventurous previous curators as Laurence Pamer and Samantha Salzinger, the center has long challenged established norms, preferring edge over ease. Current curator Jane Hart has pushed things even further, especially with the Project Room, which presents small shows of the sort you'd be unlikely to find anywhere else in the area.
