The conductor reflects on his career and the future. “The thing of which I’m most proud is the American composers of my generation that we’ve been able to work with on an ongoing and regular basis,” he says. He singles out three in particular: Christopher Theofanidis, Jennifer Higdon, and Osvaldo Golijov. “It’s great to have an American composer of about 40 years old being mobbed in the lobby — and not because people are upset but because they loved it, which happens to Jennifer.”
