J.D. SHELBURNE: KENTUCKY NATIVE WITH HITS ‘FARMBOY’ AND ‘GRANDMA & GARTH’

Country artist J.D. Shelburne grew up on a tobacco farm in Taylorsville, Ky., a tiny town southeast of the Ohio River near Louisville. At age 19, he found a guitar after the death of his grandmother and began learning to play and sing on his own. By his sophomore year of college, he had found a few gigs at some local bars in the Louisville and Lexington areas and developed a fan base that eventually landed him on some of the biggest stages in the business, opening for some of the nation's hottest stars. Eventually, Shelburne was adding original songs into the set mix, in addition to producing songs of his own material. Twelve years later he is soaking up country music, touring cities, building a fan base and celebrating a decade of success playing venues all across the southeast trying to get his big break. Today he’s among the most hardworking and relevant country singers in the business, with the hits “Farmboy” and “Grandma & Garth.” They say Nashville doesn’t work that way anymore – that talented musicians with very few connections don’t stand a chance, but J.D. Shelburne proved that Music City’s engine still runs off talent and persistence. Critics find him credible. Fans pack his shows. Venues strive to book him. There are very few new artists recording songs today about whom that can be said.
