I’m a huge fan of Bill Kirchen, Robbie Fulks, and Redd Volkaert; amazing chops and killer vocals. I’ve always been curious how those guys -- as well as other people that have had success singing roots music -- have developed their voices. I’m sure it comes down to practice and the question of just how bad do you want to be a good singer? But, love to hear of some techniques and resources people have used and found successful. Anybody take lessons? Did you find them helpful? I've been working through 90 Days to Sight Reading Success. Lots of good little exercises in various keys and CD comes along as a point of reference.
