Sturgill Simpson is a new one I've recently found, and his album is fantastic. Also gotta give an honorable mention to Split Lip Rayfield, they might be more bluegrass.

Edit: Forgot about Scott H. Biram, really love his songs

Hoyt Axton- My Griffin is Gone
Rodney Crowell- Ain't Living Long Like This
Albert Lee- Speechless
