To kick off the annual CMA Music Festival, the Cannery Ballroom in Nashville hosted one hell of a pre-party, complete with a Photo Booth, games and of course – music. Given her successful year, Kelsea Ballerini was the obvious choice for the event. The singer/songwriter performed hits from her debut album, The First Time, as well as a brand new song that is expected to appear on her second full-length. She also surprised the crowd with Hunter Hayes (not pictured) and Hillary Scott from Lady Antebellum. Check out some photos from the show!
