Pentatonix
Eclectic a capella group Pentatonix have had a fantastic past few years. November 2013's PTX, vol II marks their third studio album since the group won NBC's televised singing competition The Sing-Off back in 2011. Since the winning performance on the show, they've embarked on two national concert tours in two years, selling out tickets in over 30 cities, and their debut album, PTX, vol I, peaked at #14 on the U.S.
