Houston Cecilia Chamber Choir led by Gonzalo Ramos and the Spiritus Ensemble led by Dr. Dan Girardot will combine to feature the haunting setting of Samuel Barber’s Adagio for Strings with the Agnus Dei (Lamb of God) text. Each group will also perform selected compositions as part of the Bravura Concert Series at the resonant All Saints’ Catholic Church in the Heights. Concerts are always free of charge, but donations are accepted.
