Yannick Nézet-Séguin “has reached the top of the orchestra game” raved The New York Times. This hot young maestro just happens to be Canadian and in this concert leads his ensemble in a program of orchestral marvels: Elgar’s crowning achievement and as-yet-unsolved musical mystery, the Enigma Variations—cameos-in-sound of friends and family; and Stéphane Tétreault solos in Tchaikovsky’s sunny and graceful Rococo Variations; plus Vaughan Williams’s ferocious and harmonically bold Symphony No. 4—an unforgettable monument to its creator.
