The five fantastic members of superstar a capella group Pentatonix stopped by What's Trending to perform a medley of Justin Bieber's "As Long as You Love Me" and Katy Perry's "Wide Awake" and chat about their debut EP, PTX Volume 1.

Having started out as a trio at Martin High School in Arlington, Texas, the group built up a following on YouTube with a cover of Lady Gaga's "Telephone," and in 2011, the new Pentatonix quintet caught the attention of the nation by winning Season 3 of NBC's reality competition "The Sing-Off."

Providing some details about the big tour, Scott Hoying says, "There's a lot of audience participation. There's new songs, old songs ... It involves the audience signing!"

And when it comes down to choosing new songs to cover, the group turns to social media, using Facebook polls and YouTube as a sort of test group.
