Chamber Music Seminar Instructors

The St. Lawrence String Quartet

The St. Lawrence String Quartet (SLSQ) has established itself among the world-class chamber ensembles of its generation. Its mission: bring every piece of music to the audience in vivid color, with pronounced communication and teamwork, and great respect to the composer. Since winning both the Banff International String Quartet Competition and Young Concert Artists International Auditions in 1992, the quartet has delighted audiences with its spontaneous, passionate, and dynamic performances. Alex Ross of The New Yorker magazine writes, “The St. Lawrence are remarkable not simply for the quality of their music making, exalted as it is, but for the joy they take in the act of connection.”
