Last night Madison Monroe opened for my friend's (Longneck Road) band. He's a local boy who attended the same high school as me. If you ever have an opportunity to see him, you should check it out. I loved his set.
I don't know Madison well enough to know if he would approve of the comparison, but to give you an idea of my impression of his music, I would say it was sort of a combination of Bryan Adams and Tom Petty. That is high praise indeed from me.
