The OSR, under the batons of Daniel Harding, will perform Jörg Widmann’s Viola Concerto with Antoine Tamestit as the soloist, followed by Wagner’s “The Ring Without Words” . In this concerto, Tamestit assumes roles that go beyond being a violist, engaging as an actor, dancer, conductor, and violist, and interacting dynamically with the orchestra. The evening’s second half is dedicated to Lorin Maazel’s arrangement of Wagner’s “Ring,” which ingeniously transforms the opera into a cohesive symphonic poem.
