George Strait in the 80s &90s. I would include Allen Jackson and even Garth somewhat, but after that nothing has been good since.
Garth kind of died on the second album for me.
Not counting prior to mid 80’s since I liked most of them, I also liked Mark Chesnut, Tracy Lawrence, Diamond Rio, Shenandoah, Wade Hayes, Chris Ledoux, Tracy Byrd (not watermelon crawl though), Zone Jones, Rick Trevino, Patty Loveless, Gary Stewart, old Reba, and Toby Keith (Blue Moon and before). Some of the artists, like Garth, made it on their first one or two albums then sold their soul to make pop sounding crap and dropped their country sound (Lonestar comes to mind).
Was never an outlaw fan. Traditional country and western swing for me.
