The Highwaymen — the ultimate country supergroup: Johnny, Willie, Waylon, and Kris. Highly recommend their live album, American Outlaws .
John R. Miller — his newest album, Heat Comes Down, is maybe a little less straight-up country, but it is excellent songwriting.
Colter Wall — Western Swing & Waltzes; Little Songs
Wilco - in the early years, they had some more “traditional” country sounds A.M.
As others have said, you can’t go wrong with John Prine or Townes van Zandt.
Bonus NRPS, Gram Parsons, and Merle Haggard
I wrote almost all of my grad school work in Vim and Emacs/Evil, in a non-compsci field! It was fantastic for editing, and I used pandoc to automate proper formatting, citations, and bibliographies for my papers and thesis. 10/10 would recommend to someone who is tech savvy or has a tangential interest in programming.
