The Chamber Orchestra of the Triangle and the Concert Singers of Cary join forces for two concerts this weekend, offering a contemporary opera and a classic choral work in both performances. Samuel Barber’s 1959 “A Hand of Bridge” is a short one-act in which four players reveal their inner frustrations, and Franz Schubert’s 1822 Mass No. 5 is a deeply moving, lyrical piece for soloists and chorus. $20.
