Here are a couple that I like. Sort of more country influenced I would say, but overall damn good music.
Austin Lucas has some Ohio ties. His father Bob Lucas lives in Logan County in Zanesfield (near Bellefontaine) and currently runs Mad River Theater works. His dad is also a blue grass musician in his own right. I saw Austin over thanks giving last year in Zanesfield playing along with his sister who I new in high school on banjo. Super nice guy. Dude has a great voice and writes some great songs. Here is a song that is off of his ablum Collection called "Go West". I believe Austin lives in Bloomington, IN.
Dylan LeBlanc is another that you might like. From Muscle Shoals, Alabama. I saw Dylan open for the Drive By Truckers last spring. He and his band were great live and his album Paupers Field is really enjoyable. This guy also has a great voice and writes some really beautiful songs. His ablum is a little bit more low key than he was live...dude rocked it out live which you can kind of see at the end of the second video.
