Perhaps the most star-studded evening in the history of television singing competitions, the hugely popular band OneRepublic performed its latest hit “Counting Stars” with competition finalist Michelle Chamuel on the season four finale of the hit NBC series The Voice. The episode also featured performances by Cher, Christina Aguilera and Pitbull, Florida Georgia Line and Nelly, Bob Seger, Hunter Hayes, and Bruno Mars. OneRepublic makes its Ravinia debut with Churchill and Mayer Hawthorne on July 23.
