What I did hear was terrific. The jazzy “Prelude, Fugue and Riffs” featuring principal clarinetist Joseph Morris was almost too hot to handle. “Chichester Psalms,” with the Pacific Chorale and boy soprano Angel Garcia, was startlingly bright. Soprano Celena Shafer sang “Glitter and Be Gay” brilliantly, though overacted. The performances were such that Bernstein, along with baseball, became a theme of the weekend, since all the other programs had works he was known for conducting.
