Arranged in the style of vocal groups like Take 6 and Straight No Chaser, and capitalizing on the renewed interest in a cappella music from television shows like The Sing-Off, David Wise has combined intricate harmonies, driving vocal bass lines, and grooving vocal percussion lines to give these Christmas carols new life! Here's Joy to the World and O Come, O Come, Emmanuel - whether performed by small groups or choirs in churches or schools, these arrangements are sure to be showstoppers! To aid in performance, various accompaniment track options are available.
