French chamber music has long been lauded for its complexity and sophistication, and nowhere is this better exemplified than in Ravel’s masterly string quartet. In this concert at Robert Knox Hall, Phoenix Collective Quartet pairs the Ravel with the work of the Chevalier de Saint-Georges, a darling of the eighteenth-century French court whose eventful life recently became the subject of the movie Chevalier. The first string quartet of Guillaume Connesson, a modern-day inheritor of Ravel’s nuanced style, completes the program.
