Looking for music similar to King Crimson’s The Devil’s Triangle

Doesn’t have to necessarily be in the prog rock genre but music that has a similar dark & eerie/otherworldly vibe to that track so it could be ambient as well, such as this…

 

The Devil's Triangle is a reworking of Gustav Holst's "Mars, the bringer of war" from "The Planets".

So, you can start there.

 

"Abaddon's Bolero", Emerson Lake & Palmer (from Trilogy)

 

Pretty much everything else I will recomend, will be prog rock.

Try the Swedish band, Anekdoten. All their albums are worth checking out. Their middle couple of releases did get a bit into the dark ambient feel, before they went more proggy again.

 

If your ear is open to a bit (well, more than a bit) of atonality and dissonance, you can't go wrong with Belgian band, Univers Zero.

Dark and intense, for sure. And masterful. Musicianship by all members.

French band, Art Zoyd is somewhat in the same vein, and almost as good.

 

Anekdoten from 2016.

 

‘Industry’ is a later, sort of revisiting of the idea.

 

If you're open to ambient, I would recommend Eno's On Land.
