The Cajun band L’Angélus is composed primarily of Rees family brothers and sisters.  Their 2006 CD was entitled Ca C’est Bon! They’re offering ten free Christmas songs on their web site.  They are all traditional, religious Christmas songs.  Give ’em your name and email and they say that you’ll receive a link to their free songs.  And they have a Christmas CD, O Night Divine.  Also available as an MP3 download.
