Jason Aldean headlined Today’s Citi Concert Series this morning (Aug. 25) in New York’s Rockefeller Plaza.

Jason’s four-song set included three of his past No. 1 hits—“Lights Come On,” “Dirt Road Anthem” and “Any Ol’ Barstool”—as well as his new single, “They Don’t Know,” which is currently No. 9 on Billboard’s Country Airplay chart.

In addition, Jason chatted with the co-hosts about getting ready for the upcoming birth of his first son with wife Brittany.

“We got a little boy on the way,” said Jason. “He’ll be here before the end of the year. It’s actually the first boy on either side of the family in quite a while. My sister has three girls, I have two. My wife’s sister has two girls. So it’s all girls, no boys. This’ll be the first one, so we’re excited.”
