Listen to Brad Paisley on iHeartRadio

Brad Paisley is performing on Saturday, September 22nd at the second annual iHeartRadio Music Festival in Las Vegas and to get ready for it, he is doing a little research on his fellow performers.

According to The Boot, Paisley says he can't wait for Calvin Harris to perform, but he doesn't know much about him including what he looks like.

"I don't even know what he looks like, because the ("Feels So Close") video is of an old man with a horse and a lasso," Paisley told The Boot. "If I saw him backstage, I won't know him. I'm going to have to do some Wikipedia."
