Don’t miss this Sunday’s musical celebration for Advent in the Chapel of The Presbyterian Church in Morristown (December 18 at 4 p.m.). Directed by Dr. Charity Wicks, the Chancel Choir will perform A Spotless Rose, a Vespers service in adoration of the Virgin Mary. This evening prayer service devoted to the mother of Jesus will include music by English and American composers Herbert Howells, Benjamin Britten, William Billings and John Leavitt amongst others, performed by soloists, choir, harp, cellos, flutes and organ. The afternoon will include settings of the ethereal O Magnum Mysterium text by two 16th-century Spanish composers, Tomás Luis de Victoria and Cristobal Morales, presented by a vocal quartet and The Recorder Consort, as well as settings of the beautiful hymn-tune, Lo, How a Rose E’re Blooming presented in various forms and styles.
