Somebody That I Used To Know - Pentatonix (Gotye cover)

Luke showed me this youtube video last year, and with all the great music on our recent Road Trip I was reminded of it again. The harmony and emotion is haunting.  I look forward to additional videos and performances from this group.  I also hope the songwriter's next arrangement is a happy song.
BTW - interesting the 'Now I Lay Me Down to Sleep' melodic phrase embedded in the tune.
