Church music director Andrew Senn will lead musicians from the Academy of Vocal Arts, Opera Philadelphia, Philadelphia Orchestra, and others in movements from the requiems of Brahms and Fauré, choral music by Mozart and Dawson, the "Nimrod" movement from Elgar's Enigma Variations, and Barber's Adagio for Strings. A freewill offering will go toward Heeding God's Call, a faith-based anti-gun-violence group, and the William Way LGBT Community Center., 215-567-0532.    - Peter Dobrin

Ehnes rules. Canadian violinist James Ehnes has long been a popular and frequent Philadelphia visitor. But even with the high standard he sets, his new Onyx-label disc of 20th-century violin sonatas by Elgar, Debussy, and Respighi suggests that he just keeps getting better. With pianist Andrew Armstrong, Ehnes uses his superprecise violin technique to get at expressive details that others may know are there, but just can't get at. The surprise in the repertoire is Respighi's Violin Sonata in B minor, suggesting that the Pines of Rome composer was more like an Italian Richard Strauss than previously known.
