Pentatonix, the Arlington-rooted a cappella group, ended a busy week with an appearance on The Tonight Show With Jay Leno -- a return to NBC, where Pentatonix won the final season of The Sing-Off a little more than a year ago.
To reiterate: Pentatonix was founded by Arlington Martin High grads Scott Hoying, Mitch Grassi and Kirstie Maldonado, who later recruited Avi Kaplan and Kevin Olusola so that they could enter The Sing-Off, which had a five-singer minimum for groups appearing on the show. Kaplan and Olusola provide the rhythm section.
But in this performance of Angels We Have Heard on High from their Christmas album, PTXmas, Kaplan takes a brief lead vocal, although Hoying, Maldonado and Grassi do the bulk of the lead work.
The group also did some non-Christmas action this week, with an appearance on Katie Couric's daytime show, which generated this web-exclusive cover of Psy's Gangnam Style:
Between concerts and TV appearances (the group also appeared on Hallmark's Home & Family, but decent video is hard to come by, the group also released a new web video, this one a medley of 'N Sync songs:
And really, the busy week hasn't ended: the group performs Saturday night in Las Vegas, and there are more upcoming concerts listed on the official Pentatonix website.
