Those elder statesmen of the Acadiana prairie; the band that has arguably done more than any other to propel the traditional music of southwest Louisiana into the twenty-first century—Steve Riley and the Mamou Playboys come home to Lafayette—to the intimate stage of the Blue Moon Saloon, specifically—to celebrate. What's to celebrate: The arrival of a new year, and a new album from these twenty-year, twice-Grammy-nominated, veterans who harmonize in seventeenth century French but somehow sound anything but dated. Steve Riley and the Mamou Playboys will play the Blue Moon to mark the release of their latest CD, with a couple of surprise special guests along for the ride. To find out who, you'll just have to go. 8 pm at 215 East Convent Street. (877) 766-2583 or http://bluemoonpresents.com.
