Pentatonix, the a cappella group founded by Arlington Martin High grads Mitch Grassi, Scott Hoying and Kirstie Maldonado, won The Sing-Off, has a couple of hit albums, gets millions of YouTube views and just returned from a European tour.
But this is the big time: Theyre hanging out with Muppets.
Pentatonix is scheduled to appear on the Friday, Feb. 7 episode of Sesame Street (11 a.m., KERA/Channel 13), , counting (and singing) to five. An advance clip shows the group singing together and as individuals -- including a couple of relatively rare lead vocals by rhythm section Avi Kaplan and Kevin Olusola, who were recruited by the original members so that the group would meet the minimum five members required for Sing-Off eligibility.

Pentatonix also released a video for a new song, Run to You, on Jan. 30. It already has more than 1.8 million views on YouTube. Its the group at its most elegant, all five voices unified to sing a haunting ballad -- practically a 180 from their Sesame Street song. Watch it here:
Flipping back to Sesame Street, Pentatonix has done a mashup of a couple of Sesame Street classics, C is for Cookie and Rubbery Ducky. Theres a little bit of a debate over which is better, but obviously anything about cookies deserves to win. This one has a Muppet cameo. Not to spoil anything, but C is also for cameo. Watch it here:
