In March, the Arod Quartet reunites with cellist Julia Hagen for a tour of Germany, from Baden-Württemberg to Schleswig-Holstein, to perform Schubert’s Two-Cello Quintet and Mozart’s “Dissonnance” Quartet. They are then returning to the United States for a tour of the country: La Jolla, Santa Barbara, Oklahoma City, Charlottesville, Bryan and Tempe.
