Plenty of good modern country music out there, you just have to look for it. Tyler Childers and Colter Wall are some famous ones that spring to mind, but there's many others.
I really love "Sarah Shook and The Disarmers" as well. They actually go by River Shook now I think, but the band still uses their dead name.
A bit more on the folk side than country, but "Nick Shoulders and The Okay Crawdads" is one of my absolute favorite bands these days. They just put out a new album too and I can't recommend it enough.
