I have been to back to back shows on this tour and the setlist was the same, but no matter..I loved every second of it and am going again in the summer. The energy and performance are just amazing.
I've not been to back to back shows, but I have seen him a few times in one year. Each time there pretty much the same show, but they do change it up alittle. Either way, Eric Church is Awesome, so I'd say go see him as often as you can.
