The Chamber Music Northwest Summer Festival continues through July 28. Grand Encounters on July 13 (8 p.m. at Kaul Auditorium) and July 14 (4 p.m. at St. Mary’s Academy) features music by Mozart, Christopher Theofanidis, and Hummel. Pianist Alessio Bax, pictured, assumes the leading role in Hummel’ s Septet in D Minor for Flute, Oboe, Horn, Viola, Cello, Bass and Piano. The piece is more like a small concerto, full of virtuosic flourish and spirit. Tickets and information at this CMNW link.
