“The San Francisco Symphony’s 2009-10 season will include six commissioned world premieres and inaugurate Project San Francisco, a new initiative featuring two-week residencies by cellist Yo-Yo Ma and composer George Benjamin.” While the symphony “has seen its endowment income drop 25 percent and trimmed its administrative costs last year,” it says ticket sales and fund-raising are steady, and it “has no plans to scale back programming.” Also, it has a new four-year contract with its musicians.
