Concertmaster Julia Cash and Principal Flute Ann Bobo bring together fellow Pro Arte Cooperative members Colin Davis, Jean Haig, and Leo Eguchi for a capricious concert featuring works for three, four, and five instruments. Valerie Coleman’s Maombi Asante grooves everything into action, followed by Mozart’s energetic Flute Quartet. Hometown-heroine Amy Beach’s Theme and Variations for Flute and String Quartet bring everyone together to round out the afternoon.
