Civil Wars Xmas single free on iTunes

FREEBIE ALERT: The iTunes Store’s free holiday single of the week is The Civil Wars’ characteristically spellbinding rendition of the traditional carol “O Come O Come Emmanuel.” It’s the B-side of the duo’s Christmas single “Tracks in the Snow,” which will set you back 99 cents. While you’re in there, check out the customer reviews, which are unreal. Here’s an example: “The Civil Wars have made 2011 such a renaissance year for music. The two songs on this single release are as beautifully done as each of the songs on the magnificent Barton Hollow album. The blending of these two’s vocals is nothing short of magic, the music is simplicity and perfection. True talent does exist, and it is contained herein!” (11/30a)
