Smith will play before Dave Stewart, of Eurythmics fame, and the main act will go on about 9:10 p.m., according to a fan advisory from concert promoters Live Nation.
Smith has been living in Nashville for seven years, but most of his formative years were spent in and around Virginia's colonial capital.
These days, he's out on the road with one of the biggest bands in country music. The Sugarland tour began April 5 in Toledo, Ohio.
"I imagine it's going to feel like I felt when I stepped in the inner circle of the Grand Ole Opry to play for the first time," he told the Toledo Blade last month. "It's one of those moments where you're overcome with emotions because you're living out your dream. You will probably see me smile a lot."
Clearly, Smith's career is heating up. Early this year, he released his debut single, "We Got Us." It'll be included on a debut album set to arrive this summer on Mercury Records, home to Sugarland.
"I wouldn't expect people to know me yet," he told the Toledo newspaper. "I feel like I'm a horse in a gate. I'm ready for that gate to open so I can come charging out. The Sugarland tour is a dream come true, and I feel like that's the gate opening."
Smith's show business prospects got an earlier boost when he was picked to be a contestant on the CBS show "Amazing Race" in 2009.
