Carrie Underwood fans who were lucky enough to score a wristband to get into her surprise Atlanta, Ga., concert on Friday night (Sept. 18) were among the first to hear the country star perform her new single, "Smoke Break," live.

Press play on the video above to watch Underwood sing the brand-new tune. Her performance, at the city's Variety Playhouse, was taped for an episode of CMT's Instant Jam series.

AJC.com reports that Underwood's set included 10 songs and was about 50 minutes long. "Smoke Break" was the only new tune that Underwood performed, but hits such as "Wasted," "Before He Cheats" and "Something in the Water" were all featured.

“I think I must be the luckiest person on the planet sometimes because I get to do this,” Underwood said from stage. “And I never thought I’d be on a stage like this in front of amazing people like you guys. Please know how grateful and thankful I am.”

The singer's Instant Jam show was announced in the early hours of Friday morning. Wristbands were given away beginning at 10AM, and, according to AJC.com, by "1:30 or so," they were all gone.

Underwood will headline the 2015 Apple Music Festival in London, England, on Monday (Sept. 21). A full-blown tour in support of her upcoming new album, Storytelleris expected, but details are still forthcoming.

Underwood’s Instant Jam installment will premiere on Oct. 17 at 10PM ET on CMT. Storyteller is set for release on Oct. 23.
