John and TJ Osborne grew up writing and playing songs for friends and family. After moving from Maryland to Nashville, they launched Brothers Osborne, a self-described "twang-and-crunch duo" that blends country and rock. The band's been a huge success, and the current tour supports last year's self-titled LP and this year's EP, Break Mine. The group performs tonight at 7 at Jacobs Pavilion. Stephen Wilson Jr. opens.
