Greg Gilpin's ever-popular anthem, which has been sung throughout the world in every voicing, has been re-imagined by the composer as an a cappella work. The introduction begins as the piano setting does with vocals dancing with light vocal jazz into the first words of “a sound of hope” and developing layer after layer into the final and bold ending. There is no lack of energy, expression or emotion in this new unaccompanied setting and will absolutely thrill a cappella choirs desiring to sing this timeless modern choral classic.
