The Dessoff Choirs’ Freedom Concert, modeled after “freedom concerts” presented by the late Coretta Scott King, offers a choral tapestry of music that reflects on events of the past while promoting hope for the future. Featured works include Ralph Vaughan Williams’ plea for peace, Dona nobis pacem (1936); Robert Sirota’s homage to the nine victims of the Mother Emanuel AME massacre, Prelude and Spiritual for Mother Emanuel; and works by three female composers. The concert closes with the well-known civil rights freedom song Oh Freedom.
