Formed as a quintet in 1987 and slimming down to a quartet in 1994, New York Voices may be slightly less well known than The Manhattan Transfer but they have trod a similarly diverse path while following firmly in the great jazz group tradition of Lambert Hendricks and Ross, Singers Unlimited and before them, the Pied Pipers and the Mel-Tones.

Silence of Time comes from their third album, What's Inside, and is written by original group member Caprice Fox. It's beautiful – and fiendishly difficult to sing!
