During their run on the a cappella talent show "The Sing-Off" in 2011, Pentatonix (Mitch Grassi, Scott Hoying, Avi Kaplan, Kirstie Maldonado, and Kevin Olusola) placed no fewer than 11 songs in the top 10 Soundtracks chart on iTunes. After their win, their YouTube channel went on to rack up tens of millions of views and their debut CD, PTX Vol. 1, entered the Billboard 200 at number 14 and the iTunes Pop chart at number one. It's arguably Pentatonix's rampant popularity, along with the success of the film Pitch Perfect, that led to NBC's decision to revive the once-canceled "Sing-Off," which just kicked off its fourth season with new judge Jewel.
Now the vocal sensations have landed in the top 10 of the Billboard Top 200 Album Chart TWICE in the past month, with their sophomore release PTX Volume 2 and the deluxe reissue of their holiday EP, PTXmas. See them perform the Christmas classic "Angels We Have Heard on High" and their original "Love Again" live in the Yahoo studio, plus hear them talk about their journey from talent-show contestants to YouTube sensations to bona fide pop stars!
