3rd Performance - Pentatonix - "Piece Of My Heart" By Janis Joplin - Sing Off - Series 3

A much better performance here than their last one. This one really brought the groove of this group back on track and i can see why they could be a major contender in the finals, especially with their beatboxer who is undoubtedly the best in the competition, though they should think about who sings what in their future songs so that the vocals aren't off-beat. B+
