Former Music Director Edo de Waart returns for the first time since 1997, introducing many listeners to the music of Franz Schreker, whose lush and dramatic work could be considered a precursor to the rich film scoring we know today. Rachmaninoffâ€Â™s sophisticated Fourth Piano Concerto is characteristic in its enormity, but with an unexpected modernness of sound. In a climactic work suitable for de Waartâ€Â™s return, Saint-Saënsâ€Â™s thundering Organ Symphony provides abundant thrills.
