Performances and compositions that represent different states of balance and stability this Friday (1/30, rebroadcast Saturday 1/31)

We turn to England for this week’s Sunday Opera (2/1 3:00 p.m.) for the only full-length opera by Sir William Walton, his 1954 treatment of a poem by Geoffrey Chaucer about the doomed love of “Troilus and Cressida." This recording from Opera North features a roster of some of the best-loved voices in British opera.

It seems as though we just went through the holidays, and we’re already starting February! To that end, we’re welcoming the month with overtures and opening numbers from ten February musicals on this week’s Dress Circle (2/1 7:00 p.m.).
