Pentatonix's New Album Debuts On Billboard Top 10

Pentatonix's new album, "PTX Vol. II" debuted in the Billboard Top 10 reports The Los Angeles Times.

The five-person a cappella group won the third season of NBC's competition series "The Sing-Off" in 2011 and have since become YouTube stars, with over 2 million subscribers and over 14 million people having watched their recent viral Daft Punk cover video.

Pentatonix has a loyal following online but their new album, "PTX Vol. II" debuted at number ten on the charts with almost no radio airplay, and needless to say, no musical instruments either. The group is currently on a sold out European tour with stops in Germany, Italy and London. Next year they will return stateside with a mammoth tour around the country, for which many of the dates have already sold out.

If the new album and tour isn't enough, you can also catch them this weekend, Sunday Nov. 17, as they will be part of a special re-broadcast of Disney Channel's hit original musical "Teen Beach Movie," featuring a cappella versions of songs from the film.

Head on over to their YouTube page to see their covers of other popular songs like Lorde's "Royals" and "Thrift Shop" and for more information on the upcoming tour, head here.
