Billy Currington certainly paid his dues before becoming a headliner in country music.

"I was here for 10 years before I got a recording deal," the singer tells The Boot. "I moved here when I was 18. I had a lot of different jobs but I poured concrete for six years."

One of the buildings he worked on while it was under construction is the Sommet Center in downtown Music City. This Saturday, Currington will headline the post-race show that closes out the 10th annual Country Music Marathon. The concert just happens to be at the venue he helped build, the Sommet Center.

"I'm sure back then I didn't know I'd be playing there one day," he says. "Saturday will be the first time I've ever played there. That's pretty cool."

Joining Currington on the show are Ashton Shepherd and The Carter Twins. More than 30,000 runners are expected to participate in the event, which benefits The Leukemia & Lymphoma Society's Team In Training program.
