The gang of pop-minded songwriters entertained the masses with hits like "Snapback" and "Break Up With Him" during a mini-set medley at the stadium on Saturday night, but the group was able to get up-close with fans and stretch its wings during Pandora's CMA Fest kickoff party on Tuesday. Onstage at local venue Marathon Music Works, Matt Ramsey and Co. offered songs off their 2015 debut Meat and Candy, and also showcased the refined sound of their upcoming Happy Endings, including current single "No Such Thing As a Broken Heart." If O.D.'s ultimate goal is being country's Maroon 5, they're well on their way. J.H.
