Dreamlike music, some of it dark and haunting, is the focus of this lovely program, conducted by Michael Tilson Thomas and featuring the superstar violinist Anne-Sophie Mutter in Berg's deeply personal Violin Concerto and "En r�ve," a work written for her by the Swiss composer Norbert Moret. Incidental music from Schubert's "Rosamunde" and Debussy's painterly "La Mer" round out the evening.
