Billy Strings, Tyler Childers, and Colter Wall are all producing really good country music. Most of it isn't playable on the radio but it's good.

Bluegrass rock is a previously unknown genre to me.  I do appreciate the skills of the bluegrass musicians. They actually play their instruments and do not fake it with the three chord stuff that is so prevalent with garage band imposters.

Another good group is Nickel Creek, but they split up.  Chris Thile from that group is an over-the-top mandolin player.
