To launch its tenth anniversary residency at the Bravo! Vail Valley Music Festival, the New York Philharmonic presents the first of six concerts on July 20, when it hosts the debut of teenage piano sensation Benjamin Grosvenor, just named one of the year's top ten Britons by London's Daily Telegraph. Among other highlights of the residency are the Vail premieres of Mozart's Mass in C minor and Nielsen's Third Symphony, both led by music director Alan Gilbert; the Second Piano Concertos of Tchaikovsky and Brahms with Festival Artistic Director Anne-Marie McDermott and powerhouse pianist Yefim Bronfman, respectively; seminal symphonies by Brahms, Tchaikovsky, and Stravinsky; guest conducting spots by Andrey Boreyko and Bramwell Tovey; and a program showcasing favorite Gershwin songs with Canadian coloratura soprano Tracy Dahl.
