Not necessarily looking for something about metal or music, but just something that matches this aesthetic. Very electric and vibrant, leather-clad (doesn't have to be an 80s film but at least reminiscent of one). On a more niche level, I am looking for something with the element of facing phantasmal forces with a knife or at least a blade of some sort, but ideally a knife. Or a film with a slasher pitted against supernatural forces.
The first one def gave me giallo vibes - something like Deed Red or Tenebrae mixed with 80s horror like Mausoleum or One Dark Night.
Neon Maniacs (1986) instantly came to mind for some reason.
Dont know specific movie titles for recommendations but i would seek out italian giallo genre tho, based on that art
My first thought was Mandy (2018).
It might be a weird connection, but what the art evokes makes me think of Final Girl.
Phenomena with Jennifer Connelly
Nightbreed (1990) springs to mind?
Demons (1985)
If you've never seen Phantasm, you should probably check it out.
