This acoustic duo consists of Cary Ann Hearst and Michael Trent. who specialize in what they call “sloppy tonk” music. Nice. Think a stripped down, cowpunk’d White Stripes. Yeah, maybe not. Listen for yourself here. Headliner Justin Townes Earle was lavishly all kinds of praise on Cary earlier that afternoon. I dug the way they would seamlessly switch instruments throughout the set.
