Umoja, a world premiere commission by American composer Valerie Coleman, launches our 2019-20 season. Ms. Coleman's spirited music draws from Afro-Cuban, jazz, and classical genres. Umoja—meaning unity in Swahili—is alive with all these influences.  Bartók's gorgeous Third Concerto, performed by Yannick's good friend Hélène Grimaud, is as vibrant today as the day The Philadelphia Orchestra and Eugene Ormandy gave the world premiere at the Academy of Music in 1946.
