Joe Kluger is stepping down as president of the Philadelphia Orchestra after 16 years. “Kluger’s tenure makes him the second-longest current chief of a major American orchestra (after Cincinnati Symphony Orchestra president Steven Monder), according to the American Symphony Orchestra League. Kluger, 50, said that he will take on a consulting role with Adrian Ellis, whose firm, AEA Consulting, specializes in facilities and operational issues for arts groups. Kluger said that he does not know if that will be a short- or long-term step in his career.”
