Before we settled in to record an interview for the Saturday night broadcast of the Symphony’s concert on St. Louis Public Radio, I asked Karita Mattila if it was all right to discuss that this will be her premiere performance of Schoenberg’s Erwartung. I asked because some artists prefer not to make that part of the story of their performance, for a host of reasons.
“Why not?” Mattila said. “I’m 53. Is that not a good time to try new things?”
