Hawking original Christmas songs has never been the easiest commercial venture, but Ohio duo Over the Rhine renounced the pursuit of mainstream success long ago. Snow Angels, its 2006 collection of wistful holiday music, didn't reach far beyond the band's devoted following, but it might be the best soundtrack since A Charlie Brown Christmas for feeling melancholy and lovesick in December. Over the Rhine's annual holiday shows promise to draw from Snow Angels and the best of their earthy, dark-roasted catalogue. The band sells its own coffee online and the piano-driven music practically begs to be mused upon over one hot drink or another. Pianist/husband Linford Detweiler crafts songs with gorgeous open spaces, and vocalist/guitarist/wife Karin Bergquist fills them with an emotional range that makes sure the meditative music still flirts and surprises.
