These international superstars are returning to their alma mater for a night of festive holiday favorites, surprising pop arrangements, and vocals that will knock your socks off.

Straight No Chaser is a master of reinventing a cappella on the modern pop landscape. Originally formed in 1996 at Indiana University, the group has reassembled and reemerged as a phenomenon with a huge fan base, millions of viewers on YouTube, and multiple albums with Atlantic Records.

Tight vocals and loose humor have catapulted these IU-born musical masterminds from local legends to international superstars, leaving in their wake a slew of chart-topping albums including 2008’s Holiday Spirits, 2009’s Christmas Cheers, 2010’s With a Twist, and last year’s Under the Influence—which featured the breakaway holiday hit “Text Me Merry Christmas” which peaked at #28 on Billboard 200.

Year after year, SNC keeps getting better at what they do best: captivating audiences with their tight, clever harmonies, and winning them over with their tongue-in-cheek charm. Their wildly entertaining a cappella concerts prompted The Trades to write, “Straight No Chaser endeared themselves to fans with ‘we-don't-take-ourselves-as-seriously-as-we-do-our-music’ antics, good humor, and heartfelt moments of self-admission.”
