The Pittsburgh Symphony is searching for a new music director to replace Mariss Jansosn. What is the orchestra looking for? “Whereas maestros Andre Previn, Lorin Maazel and Jansons were picked because they could be marketed, the next music director will have to do the marketing. At least, that’s the case in mid-sized markets such as Pittsburgh. A large part of the perception of the orchestra and its marketing ability flow through the podium. Previously, the maestro’s reputation leaked into marketing in an indirect way; now, he or she will be on the front lines of fund raising and ticket selling.”
