Grammy-winning conductor Alan Gilbert makes major festival appearances on both sides of the Atlantic this summer. In a weeklong residency at the Tanglewood Music Festival, he leads multiple programs with the Boston Symphony Orchestra and gives a talk about “The Art of Conducting” (Aug 2–9). As Chief Conductor of the NDR Elbphilharmonie Orchestra, he follows the NDR’s season finale in Hamburg (June 28–30) with opening-night concerts at Germany’s Schleswig-Holstein Music Festival (July 6 & 7) and the closing-night concert of Switzerland’s Lucerne Festival, where their star-studded account of Schoenberg’s Gurre-Lieder takes place just two days after the 150th anniversary of the composer’s birth (Sep 15). Gilbert completes his summer lineup in Japan, with two programs as Principal Guest Conductor of the Tokyo Metropolitan Symphony (July 15–24).
