Expect to be deeply moved by the soprano and alto voices of the Trinity Choir during this evening of choral music that glorifies Mary, compassion, and the spirit of Lent. With Hildegard von Bingen’s luminous Ave generosa at its center, the program also presents Francis Poulenc’s Litanies à la Vierge noire and Marian gems by Maurice Duruflé, Bernat Vivancos, Edvard Grieg, and Ola Gjeilo. A trio of newer composers  (Zanaida  Stewart Robles, Ily Matthew Maniano, and Margaret Rizza) add their perspectives to timeless themes of mercy, devotion, and divine joy.
