This concert highlights the music of three American composers. First up is Florence Price’s Ethiopia’s Shadow in America, which charts the arrival of Africans in America. Then, superstar soprano Julia Bullock sings a Sun Valley Music Festival commission, the world premiere of Jessie Montgomery’s Five Freedom Songs based on traditional African American spirituals. And finally, Ms. Bullock will narrate Aaron Copland’s iconic Lincoln Portrait, featuring excerpts from President Lincoln’s speeches, in particular, the Gettysburg Address.
