While in town after the tour's New York stop this past Sunday (July 21), Kramer sat down with Radio.com and filled us in on what it's like to watch Shelton, both on stage and behind the scenes.

"He's an amazing entertainer," Kramer said. "He really interacts with the crowd, and he has them his hands. He's just so good with talking to them and the way that he expresses his songs and shows his emotions."

One song in particular had Kramer tearing up. "He was singing 'Over You,' and I was crying," she said. Kramer is referring to the chart-topping, ACM award-winning song he wrote with his wife, Miranda Lambert.

"He's fantastic," Kramer continued. "He's energetic. And the way he treats his crew is very respectful. I like that."
