Our May concert will feature excerpts from Mozart’s Requiem, plus a selection of short pieces, including Duruflé’s “Ubi Caritas,” Mendelssohn’s “Psalm 43,” and “David’s Lamentation” from The Singing Master’s Assistant by William Billings (considered by some to be the father of American choral music). Other works include “This Marriage” by Eric Whitacre, “Agnus Dei” by Lithuanian composer Kristina Vasiliauskaite, Gwyneth Walker’s “The Rose, the Briar, and the Bicycle,” “Carol of the Stranger” by Abbie Betinis (with words by poet Michael Dennis Browne), and “Crystal Spheres” by Cecilia McDowall, set to Milton’s 1629 ode “On the Morning of Christ’s Nativity.”
