If there's one virtuosic singer out there who can take on songs as tried-and-true as Christmas carols and still make them unquestionably her own, it has to be Barbra. Between her iconoclastic personality, magnificent voice, and nimble interpretive ability, she makes these age-old classics sound like we've never heard them before. She darts rapturously through a playful, tongue-in-cheek version of "Jingle Bells" at one moment, and yanks at our heartstrings the next with her swelling, evocative rendition of "Silent Night."
