What country music would you recommend to someone who wants to listen to some country that isn't bro/truck country? I know not all country music is Like That but unfortunately at the moment that's most of my experience with the genre and I want to broaden my horizons. Maybe some good gothic country or bluegrass suggestions?

(I am, of course, already familiar with Johnny Cash and Dolly Parton. Beyond that feel free to suggest even extremely obvious choices)
