A large percentage of the American art world seems to accept, without argument, the idea that New York is the art center of the world, and has no peer. But the dean of the Yale School of Art and curator of next year’s Venice Biennale is on a mission to get artists and art lovers to look beyond New York, which he says is overvalued to a ridiculous degree. Robert Storr says that the most interesting modern art is coming from Asia and Africa, that the best-run museum in the country is in Minneapolis, and that the art world’s obsession with money allows the New York-centric viewpoint to thrive.
