After nailing a capella covers of Gotye's "Somebody That I Used To Know" and Katy Perry's "E.T.," The Sing-Off's winning group Pentatonix has taken on fun.'s chart-topping teen anthem "We Are Young." The cover -- arguably the group's best yet -- has gotten nearly 300,000 views since it was posted on Monday, and even made it to the front page of Reddit.
The group is comprised of vocalists Scott Hoying, Mitch Grassi, Kirstie Maldonado Avi Kaplan and Kevin Olusola. Scott, Mitch and Kirstie went to high school together in Arlington, Texas, where they started out as a trio. With Avi and Kevin, the quintent rose to prominence when they won the third season of NBC's The Sing-Off last year with a kick-ass cover of Eye of The Tiger, earning them a $200,000 contract with Sony. Since then, the group has been pumping out one hit viral video after another, and they are currently in the studio working on their debut EP.
