Flashes of illumination and primal darkness take turns in this program inspired by humanity’s cosmic struggle between the forces of light and dark. A joyful Bach cantata bursts forth with jubilant trumpet and exaltation before a Renaissance lute song is refracted and illuminated through a contemporary lens. At the opposite end of the spectrum, Bolcom’s masterful mid-century rags for two pianos tell the story of the Fall, lending a lightness to a very dark theme. Expelled from the paradise of his Polish homeland in World War II, Weinberg mixes traditional and contemporary forms, combining inspiration from his close colleague Shostakovich with ethnic (Jewish, Polish, Moldovian) influences and a unique sense of style.
