A former student sent me a notice that caught my attention, for both artistic and pious reasons. The Cantata Singers of Ottawa will be at St. Joseph’s Church later this month where the entire program will consist of settings of the brief Eucharistic and Marian hymn, Ave Verum, including those of Lassus, Byrd, Mozart, Elgar, Liszt, Saint-Saëns and Poulenc.
