CALIGULA by Lingua Ignota can be pretty disturbing, it was written as a way to process the trauma of their experiences with sexual assault.
Casualties of Cool by Devin Townsend can be kind of uncanny. Its supposed to be a concept album that sounds like a “haunted johnny cash album” the songs are good but a lot of the sound effects and such are really creepy
Some of the classics beyond cash and dolly, I’ll exclude the more countrypolitan stuff, these are mostly more honky tonk, also some modern people
Hank williams (all three of 'em) merle haggard, willy nelson, waylon jennings, kris Kristofferson, Buck Owens, wayne hancock, Orville peck, marty robbins, nick shoulders
Bluegrass earl scruggs, osborne brothers, ricky skaggs, billy strings
Gothic? Bridge City sinners, rhiannon Giddens, Amigo the Devil, Shawn James
