Viola Visions officially commences with this welcome concert featuring viola-centric works spanning more than 300 years of repertoire. MTT leads Cynthia Phelps (New York Philharmonic), Jonathan Vinocour (San Francisco Symphony) and Tabea Zimmermann in J.S. Bach’s final Brandenburg Concerto and the virtuosic variations of “Les folies d’Espagne” arranged by Irish-born violist Garth Knox. Inspired by a racing video game, Andrew Norman’s Gran Turismo has eight violists locked in a highspeed chase.
