The Haven Quartet's a cappella Christmas includes Bach's 'Jesu, Joy Of Man's Desiring,' 'Silent Night,' 'Go Tell It On The Mountain' and the 'Wexford Carol,' among others. In other words, whether an Irish traditional, American spiritual or Alfred Burt carol, the common thread is the versatility of this Contemporary Christian group. 'Mary, Did You Know' is revitalized, with a soulful lead by Randy Crenshaw, transforming it into an emotional pop ballad; the resonant 'Noel! Noel!', augmented by a refrain played on recorder, and a lively renaissance country-dance rhythm, is joyful and festive. Each Haven member's voice possesses an attractive brilliance of tone, and the four voices together have an exceptional depth.
