I wouldn’t say these are obscure but could be interesting if you are somewhat adventurous.
The Cramps - Bad Music for Bad People (spooky psychobilly)
Big Black - Atomizer (aggressive, dark, shadowy)
Orbital - Middle of Nowhere (aggressive, semi-complex electronica. Not EDM)
69 Cats - Transylvanian Tapes (gothabilly)
Love and Rockets - Lift (Spacey, 90’s psychedelia)
These are not albums but they are fun
Camper Van Beethoven - Take the Skinheads Bowling (alternative power pop)
Big Black - Racer X (misplaced angst)
The Residents - Kaw-Liga (Hank Williams meets Thriller era Micheal Jackson) actually its Doug & Rusty Kershaw meet Micheal Jackson, but you get the picture.
