Serenade began quietly with solo violin, and at first, St. John's stature (just under 6 feet) overshadowed her playing. That soon changed. Aggressive and committed, St. John was as physical in her performance as Bernstein once was conducting. Shifting her balance like a fighter, lunging into fortissiomo endings, swaying through lyrical passages, St. John seemed to sing; the music seemed to rise from deep inside her and through the violin.
