There's some great stuff nowadays that isn't just bro country! It's going to be mostly smaller and all my favorites lean heavily into their bluegrass and folk roots, but there's some great stuff!
I'd check out Tyler Childers or Zach Bryan for something more mainstream. I might get flamed for calling them country, but Poor Man's Poison is fantastic as well!
If you don't love Chris Stapleton after one listen of Tennessee Whiskey, then idk what to tell you
