Kyung Wha Chung's hushed phrasing of the ethereal opening theme is full of wonder . . . and Andre Previn and the London Symphony Orchestra make perfect travelling companions on the Nordic journey that follows. . . . The Adagio is lovingly moulded and the finale . . . swaggers just as it should. Decca's superb engineering and the Kingsway Hall's acousting are the icing on the cake.
