Joshua Hedley is "a singing professor of country & western,” he declares on his new album, Neon Blue. As an ace fiddle player, a sharp guitarist, and a singer with a granite twang, Hedley has been a presence in Nashville for nearly twenty years; although you have to know where to find him. You have to brave the tourists on Broadway, bypass the three-story bars blasting Journey, and make your way to Robert’s Western World, a time-capsule honkytonk from a different era, an oasis in a town where twang is constantly being run down by pedal pubs.
