An estimated 25,000 people jammed Nashville’s Lower Broadway last night (Oct. 17) for Capitol Records' fifth annual street party, featuring headliner Luke Bryan and newcomers Kelleigh Bannen and Jon Pardi.

The crowd was already shoulder-to-shoulder when Kelleigh kicked things off with a 30-minute set that included her debut single, “Sorry on the Rocks.” "Missin' You Crazy" singer Jon Pardi followed with a high-energy 45 minutes that included a cover of labelmate Eric Church's "Drink in My Hand." If the crowd was enthusiastic for the two openers, it came downright unhinged for main attraction Luke.

Luke's hourlong set had little banter between songs, but instead was dominated by performances of his hits, including "Rain Is a Good Thing," "Do I" and "Country Girl (Shake It for Me)." Working the catwalk that extended well into the heaving crowd, Luke's steps were littered with items being thrown at his feet. When he finally stopped to fling the umpteenth undergarment off the stage, he announced, "Nashville wins the bra-chunkin' contest, don't they!" And even he succumbed to the fun of a cover song—especially when pal Dierks Bentley stepped onstage to sing half of Brooks & Dunn's "My Next Broken Heart."

Pounds of confetti showered the air and a breathtaking fireworks display finished off the biggest Capitol Street Party to date. Still, the best show was undoubtedly what happened onstage.
