Turns out, it's also a milestone: "Smoke" is the first debut single by a new country group to top the Billboard Country Airplay chart in this decade (the last to do it was Zac Brown Band with their debut single "Chicken Fried" in 2008).

"Smoke" is also just the first taste of what's to come on Southernality, the group's debut album. Produced by Dave Cobb (Chris Stapleton, Jason Isbell, Sturgill Simpson), the album drops June 9.

As the bandmembers explain, the success they've had with "Smoke" proves there is still a place for Southern rock on country radio. "Bands like Lyrnyd Skynryd and the Allman Brothers, they probably would have been considered country music in some ways," guitarist Zach Brown tells Radio.com.
