Ronnie Dunn surprised fans who were in downtown Nashville for CMA Music Festival activities on Wednesday night (June 5). The singer staged an unannounced performance from atop the rooftop patio of Music City's famed Rippy's Bar and Grill on Broadway, where he debuted four new songs.

Dunn has been working on songs for a new album that he intends to release in the fall, and he gave fans who were departing the CMT Music Awards at the Bridgestone Arena a taste of 'Country This, 'Cowgirls Rock 'N' Roll,' 'Kiss You There' and 'Peace, Love and Country Music.' During 'Kiss You There,' a flash mob took over Broadway.

Since leaving Sony last June, Dunn has been developing alternative ways to engage his fans and share new music in a way that doesn't rely so heavily on the traditional Nashville business model. "I'm more excited about where music is today than I ever have been. We no longer have to play by rules because there are no rules," he tells USA Today.

"The band and crew snuck in and set up to ambush the unsuspecting crowd coming out of the CMT Awards," he adds. "We don't have a clue what we're doing, but we're having fun and working overtime to come up with unorthodox ways to get music to people who simply like music. I hope that those of you who rambled into the line of fire had a good time!"

Both 'Country This' and 'Kiss You There' are available for download exclusively at iTunes.
