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:

Zach Bryan didn't mind being upstaged by this cancer survivor during a recent show at San Francisco's Golden Gate Park.

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

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.
