I'm ambivalent about Christmas albums. I enjoy my Boston Pops album immensely, but pop star versions of the classics leave me cold (of course, they play incessantly in stores - as if Christmas shopping weren't stressful enough). The one exception is the Chris Isaak Christmas album. Yes, I am biased to love all things CI, but his retro, beachy, rockabilly vibe is a wonderful change of pace every December. While his original songs ("Brightest Star", "Last Month of the Year, "Gotta Be Good") are my favorites, he also puts a fun new spin on the classics. The only weak spot is his duet with Stevie Nicks. I like him. I like her. Together? Not so much.
Here's a sample from YouTube. Enjoy!
