While he started the night with an amazing performance of "Outstanding In Our Field" next to Hunter Hayes and Dierks Bentley, Brad took the stage with a more contemporary artist: John Mayer.

This is one of John Mayer's first live appearances in over two year since his temporary retirement to treat the granulomas on his vocal chords. He joined Brad to perform the second single off his April 9 release Wheelhouse, a 17-track album chock full of summer-friendly, windows-down songs that fans have been dying to get their hands on.
