This disc, marking the quarter-century anniversary of this a cappella vocal group, is full of emotion and integrity. Continuing to explore the textures and rhythms of the human voice, they offer such tunes as Bob Marley's "Redemption Song" and Thomas Dorsey's "Standing by the Bedside of a Neighbor." While the undeniable "granola factor" of this music, with its human rights bent, may be too much for some listeners, it's a fine addition to their catalog.
