BSO Music Director Andris Nelsons is joined by the dynamic soprano Nicole Cabell for this all-American program. The BSO premiered Samuel Barber’s gorgeously nostalgic Knoxville: Summer of 1915, based on a text by James Agee, in 1948. Complimenting Barber’s small-city observations is George Gershwin’s exuberant, jazzy, and occasionally homesick tone poem An American in Paris. The multifaceted American pianist Aaron Diehl joins the orchestra for Duke Ellington’s New World A-Coming, transcribed from Ellington’s 1943 Carnegie Hall performance. Opening the program is Washington, D.C.-based composer Carlos Simon’s Motherboxx Connection, a 2021 piece inspired by the Afrofuturist-leaning artist collective Black Kirby.
