Acoustix are one of the most consistently impressive barbershop groups performing today. "Cool Yule," their first holiday-themed recording, will add to their legend. Greg Volk arranged several songs, including "You're A Mean One, Mr. Grinch," (sung by bass Joel Rutherford, who also contributed two arrangements). Two Beach Boys scores, "Auld Lang Syne" and "Little Saint Nick," and a Mervyn Warren (of Take 6) chart, "The First Noel," show the quartet's burgeoning versatility, and it sounds great. For those listeners who prefer Acoustix to stay close to their barbershop origins, the locked-in chords of "O Little Town Of Bethlehem" and "Mary Had A Baby" will be a treat. About half accompanied in swinging big band style.
