If you were one of the millions who watched last night's ACM Awards then you got to preview something Brad Paisley's going to be doing on his upcoming Beat This Summer Tour.
Fans in the audience were given a special Brad Paisley app that synced up their smartphones to light up at special times during the performance.
This is the first time Paisley has used the app, but he will reportedly use it on his upcoming tour.
"We are going to do some really cool things throughout the tour with this app," Brian Kaplan, digital marketing manager at Sony Music Nashville, told Mashable.
