The sound recording is of the song "Oh, My Lord" from the motion picture "Glory." The recording is a portrayal of a pre-battle song by the 54th Regiment Massachusetts Volunteer Infantry, one of the first African American units during the Civil War, before their attack on Fort Wagner. The song is comprised of vocalists, tambourines, and harmonicas.
