All-star collaborations were the order early during the 2013 ACM Awards performances in Las Vegas on Sunday night (April 7). Even Eric Church's acoustic performance of 'Like Jesus Does' turned into a duet. Blake Shelton, Sheryl Crow, Luke Bryan and Pistol Annies began the show performing 'Boys 'Round Here.' It was an electric introduction to country music's biggest party. 

Brad Paisley was joined by Dierks Bentley and Hunter Hayes to sing his new song 'Outstanding in Our Field.' Then, George Strait performed his current single 'Give It All We Got Tonight.'
