The Chicago Symphony doesn’t seem to be in any big hurry to choose a successor to outgoing music director Daniel Barenboim, but John van Rhein says that the orchestra can afford to take its time. “It seems that the more people who are heard from, the lengthier the job description for CSO music director becomes. Beyond being a superior conductor, a fine musician and a strong leader who’s respected by the orchestra, he or she should be thoroughly familiar with how American orchestras function in a changing social and economic landscape. And the next music director should be willing to help the organization stump for funds, a role Barenboim has declined to play but one that has become essential.”
