Musical stylings
Nashville Gab wrote that "He is explosive on stage and completely unpredictable. I compare his live set to a wild horse, it's not meant to be tamed. He brings a blue-collar, redneck edge to every show that seems to be lacking in country music these days. Chris Janson is the future of country music..."
