Give a listen to “Music inspired by the snowgoose” by camel.
They were a psychedelic /progressive rock band from the UK who wanted to write an album based on a short story called The snowgoose. The author wasn’t a fan, unbelievably, so they scratched the lyrics and added “music inspired by” to the album title. The whole album is a journey that I can’t recommend enough!
You could give Italo Disco a try, which is a predecessor to synthwave and a lot of electronic dance music.
A contemporary niche cousin that I liked to listen to a few years back is giallo disco, which is a contemporary imitation of dark synth music inspired by 80s Italian horror movies.
From there I progressed to trance and house, acid techno and other synth heavy dance music genres.
