Chris Stapleton had to cancel his Sunday night stadium set after a finger injury impeded his guitar playing, but the rest of the lineup carried on his spirit by absolutely shredding on the guitar. As much as the evening was about country hits, Brothers Osborne (in the Stapleton slot), Keith Urban and Brad Paisley showed how the genre can be home to some of music's finest axe folk. Urban milked "John Cougar, John Deere, John 3:16" into a lengthy jam, swapping instruments midstream and at one point ending up flat on his back, while Paisley, in the last set of the night, drew visible gasps from the audience as he packed a million notes per minute into songs like "Alcohol," easily showcasing why he's one of Mick Jagger's favorites. But the biggest unplanned victory came from BROS' John Osborne, who slid "Stay a Little Longer" and "It Ain't My Fault" into down and dirty extended solos, ending the latter by raising his hands above his head in euphoria.
