Hailed as “virtuosic (WBUR Radio) for its “creative, sympathetic players…and cornucopia of unusual, extended-technique sounds (The Boston Globe),” the Ecce ensemble continues its 11th season with a one-night only concert spotlighting the innovative French composer Phillipe Leroux. Program includes the American premiere of Leroux’s triptych for chamber ensemble, L’épais, as well as a special performance of Anima (2012) for quintet in tribute to Swiss composer Dominique Schafer.
