Zach Bryan performed the last of 7 big Golden Gate Park concerts, a number that also included Outside Lands and Grateful Dead celebration.

On stage in San Francisco, Zach Bryan and Kings of Leon debuted a brand-new, unreleased song titled “We’re Onto Something.” It carries the same honesty as “Bowery,” but with a little more edge, leaving fans completely locked in from the first note. The crowd swayed as Bryan and Caleb Followill’s voices blended together on the chorus:

With Zach Bryan leading the way, Kings of Leon, Turnpike Troubadours and Noeline Hofmann will take fans on a musical journey through America’s heartland in the breathtakingly beautiful natural setting that is Golden Gate Park. This magical location and exceptional lineup of artists is guaranteed to give fans a once in a lifetime experience.

Golden Gate Park’s website says that Zach Bryan will perform at the park on Aug. 15. The show features Bryan, Kings of Leon, Turnpike Troubadours and Noeline Hofmann performing at Polo Field.

Zach Bryan says to the crowd before he lets the fan introduce himself. Hayden, the fan, got strapped up with an acoustic guitar and shared with the audience that he hails from South Dakota. What a haul to head to Red Rocks and then San Fran to see the Oklahoma native.

Country star Zach Bryan vowed over the weekend he'll fly like an Eagle over Kansas City and never play that town again
