Pentatonix, the A cappella group who won Season 3 of NBC’s The Sing Off, continue to show off their amazing talent on YouTube. The group’s newest arrangement of Pharrell‘s “Happy” is a must-watch!
The quintet is made up of Scott Hoying, Kirstie Maldonado, Mitch Grassi, Avi Kaplan, and beat-boxer Kevin “K.O.” Olusola, and they’ve graced us with memorable covers of hits from Daft Punk, Lorde, and Macklemore.
