If you're invested in the long-running rivalry between England's two most storied universities, you'll have no trouble choosing between these holiday CDs. But for the rest of us, both offer elegantly festive tunes with which to celebrate the season. Christmas from Cambridge features the Choir of Queens' College, Cambridge, performing nineteen tunes covering a millennium of music, including plainsong and organ-accompanied versions of "The holly and the ivy," "Swete was the song the Virgine soong," and "Toccata on 'Veni Emmanuel.'" Christmas from Oxford, from Worcester College, Oxford, offers more familiar fare, like "Once in royal David's city," "In the bleak midwinter," and "O come, all ye faithful." Running time: over 1 hour each.
