Straight No Chaser's 2013 EP Under the Influence: Holiday Edition is the a cappella group's fourth holiday-related release and first since 2010's All I Want for Christmas. The EP also follows up the group's 2013 studio album, Under the Influence. As with that album, Under the Influence: Holiday Edition features guest appearances by some of the band's favorite artists. Here we get a handful of holiday classics, half of which feature guest singers including Paul McCartney, Colbie Caillat, Cee Lo Green, and Otis Redding.
