The season finale features a celebration of American voices and symphonic grandeur. Valerie Coleman’s Seven O’Clock Shout, written in honor of frontline workers during the pandemic, leads into Peter Boyer’s patriotic Rhapsody in Red, White, and Blue, performed by guest pianist Jeffrey Biegel. Howard Hanson’s choral-orchestral Song of Democracy and Respighi’s sweeping Pines of Rome bring the season to a majestic close.
