The headliner is Antonín Dvořák’s Quintet of 1893, American, a rich work that reaches for the composer’s native Bohemia through the sounds of a summer he spent in Spillville, Iowa. The program begins with Southland Sketches by African American Harry Burleigh, drops in on Leonard Bernstein, and culminates with the Appalachian Spring Suite, Aaron Copeland’s concert version of the 1944 nativity play he made with modern dancer Martha Graham: America was the newborn. —L.J.
