Lost Bayou Ramblers begin Duke Performances’ 2017/18 season with an exclamation mark. Before joining the North Carolina Symphony to perform the score for Beasts of the Southern Wild, the Ramblers — a Cajun family band with influences that include garage rock and punk — will rattle the walls of the downtown Durham rock club the Pinhook. Singer Louis Michot “possesses one of the great keening voices of Cajun music,” according to The New York Times, and thanks in part to him the Ramblers have netted a GRAMMY nomination, tour dates with Arcade Fire, and a significant role in Beasts of the Southern Wild. The band shares the stage at the Pinhook with local collective Shamu Garçon, whose spirited mix of Cajun and country tunes offers the night’s ideal preamble.
