The three-time Grammy Award-winning and multi-platinum selling a capella supergroup PENTATONIX — wow, that’s a mouthful — will be returning to NBC this season for their third holiday musical special, “Pentatonix: A Not So Silent Night”!

We’ll join PTX (as they’re often referred) members Scott Hoying, Mitch Grassi, Kirstin Maldonado, Kevin Olusola, and Matt Sallee in Las Vegas as they spread cheer along the legendary Strip, including the iconic Caesars Palace and the stunning Eiffel Tower at Paris Las Vegas. Along the way, they’ll be joined by additional guests to help them celebrate, including Kelly Clarkson and Maren Morris. Both singers appear on the latest Pentatonix holiday album, Christmas is Here!.
