I own 50+ Christmas CDs. The majority in the jazz vein, and they sit on the shelf waiting for Dec to come around. I would like to recommend two:
Dwight Yoakam - Come On Christmas. Dwight gives his own take on many Christmas classics, including a Tex/Mex treatment on Silver Bells, plus two original Christmas songs. A perennial favorite on our system.
BB King - A Christmas Celebration of Hope. Strangely enough, I find this LP to be some of his best vocal work. IMHO.
Seasons greeting all.
