This Sunday the St. Michael’s Singers will offer Paul Manz’s most frequently performed composition, the 1953 motet “E’en so, Lord Jesus, quickly come.” Often sung during Advent, the text is adapted by Ruth Manz from the Book of Revelation and was composed as a plea when their three-year-old son was critically ill. Thankfully the child survived, and the composition is now a core piece of 20th century sacred choral literature. Other musical selections on Sunday include organ voluntaries by the great, perhaps under-appreciated 19th century Bavarian composer Josef Rheinberger (1839-1901) and a communion motet by the contemporary British composer and conductor John Rutter (b. 1945).
