Daniil Trifonov kicks off the summer festival season with two U.S. appearances before making his way to Europe. At Tanglewood, he joins trumpeter Thomas Rolfs, Music Director Andris Nelsons, and the Boston Symphony Orchestra for the First Piano Concerto by Shostakovich (July 19).  Next, Trifonov gives two performances at the Aspen Music Festival. Before playing Glazunov’s Second Piano Concerto with Dima Slobodeniouk and the Aspen Festival Orchestra (July 26), he gives a solo recital pairing Robert Schumann’s First Piano Sonata with three Russian rarities: Taneyev’s Prelude and Fugue, Myaskovsky’s Second Piano Sonata, and the evocative miniatures of Prokofiev’s Mimoletnosti (“Visions Fugitives”). The performance will be streamed live and available on Stage+  (July 22).
