I just yesterday ordered this one from the CBC shop, thinking it quite interesting.
"Sounds of the Season brings together some of Canada’s brightest stars as they interpret their favorite traditional and not so traditional holiday carols. The musical styles are as diverse as the carols themselves exploring the influences of hip hop, reggae, gospel blues, R & B, Latin and global rhythms."
Also, this one is pretty wild! The Little Drummer Boy/Silent Night/Auld Lang Syne medley is beautiful!
