For this concert, 11/14/12 at Lincoln Hall in Chicago, Mitch Grassi (high tenor) was sick. Instead of performing the songs that feature Mitch as a soloist, Pentatonix decided to showcase its non-acappella talents :D
I love how everyone stops hollering/whooping exactly when Avi starts singing. Nice to see a live video of him singing where you can actually hear him instead of the audience all the time.
