Mikhail Baryshnikov has worn many hats over the years, but these days, all his energy is going into the development of the new Baryshnikov Arts Center in midtown Manhattan. The center, for which he is hoping to raise $25 million, is designed to encourage collaboration between artists, and its namesake is clearly excited about the possibilities: “Musicians, artists, costume designers, lighting designers, playwrights, choreographers, actors will meet to work on the same projects. It will be a private place with no pressure from outside, where people can exchange their ideas. It’s a bit of a socialist idea, but what the hell!”
