I decided to check out some of the Dark Ambient artists you mentioned. I love streaming new artists I read about on this list except some of them are so obscure, I can't find them. Anyway, Rhapsody had the first two you mentioned. I'm streaming now through my Sonos speakers as I ready for work. I like Ambient music overall. This is really interesting stuff. A little like weirder Sunn without the lowend if that makes any sense. Or Swans instrumental passages.....I think OM would be the most logical extension fromthis kind of music. YOB is much more "metal".
One think I found amusing, Rhapsody listed these acts as EDM and listed Daft Punk as a similar artists-not!! Very cinematic, the calm before the storm in a horror film or surreal planet with fog right before the beast unleashes from the depths....that's the kind of vibe I'm getting.
Yea, those artists I mentioned are definitely Ambient. Nothing Metal about them in their structure. Kammarheit and Northaunt are two of my favorite... so much space to explore in their music. It's definitely not EDM or related to Daft Punk, haha.
Anyway, if you're diggin' on Dark Ambient you should check out some of the other giants of the genre like Lustmord, Atrium Carceri, and Raison D'etre. They'll take you on a mysterious ride for sure.
