The Saratoga Performing Arts Center’s executive leaders held their annual meeting this week, and the good news was that, after several years of deficits, SPAC finished better than $100,000 in the black this past season. The bad news is that the center’s members and subscribers are furious with the management for dumping New York City Ballet from the roster of guest artists, and several are already making plans to oust board members in next year’s board elections. SPAC officials are sticking to their guns, though, insisting that “attendance ultimately will determine the future of all classical programming, including ballet, the Philadelphia Orchestra and a chamber music festival.”
