nah i dont want to hear something EXACTLY like EDS, i just want another dark ambient dimension to step into like that of Electric Doom Synthesis! I dont mind Dark Ages, their stuff is pretty cool, but its not deep, its creepy and thats about it. I'll try those others that you have mentioned though, Thanks!
Ignore everyone else's recommendations, because they're wrong
Maeror Tri - Meditamentum I and II, The Beauty of Sadness. These range from soft, distant, slowly evolving or simply repeating guitar lines over drones to tribal drumming to a soundtrack of the explosions inside the Earth. Meditamentum II is probably the best album to start to get a good idea of their sound. Oh, it's also really good. ( http://www.youtube.com/watch?v=8PVdFf0nOzw&feature=related
, most of their "darker" songs aren't on youtube, so you're probably just better off downloading one of the albums if that's what you want to hear.)
Troum - Tjukurrpa Pt. 1 Harmonies. See above, two of the original members of Maeror Tri. ( http://www.youtube.com/watch?v=kTj0R3tbas4&feature=related
Endura - Black Eden, Great God Pan, Elder Signs - These albums probably make up the best of ritualistic dark ambient. Then again, I think most dark ambient (ie, spooky noises of rocks falling in wells) sucks so my opinion is probably moot. Anyway, they range from not that abstract (relative to most boring dark ambient bands) drones, to repetive synthesized epics not totally dissimilar to EDS, to Dead Can Dance like ballads (think the songs that Brendan Perry sings in, but more restrained and repetitive http://www.youtube.com/watch?v=utX1PN4fSG4
VS. Dark Face of Eve off of Great God Pan). (http://www.youtube.com/watch?v=Wah2fZ6ATeQ&feature=related
Aphex Twin - Selected Ambient Works Volume II - This album isn't dark ambient, nor is it alike EDS in sound or structure, but some of the darker songs do create a similar sense of foreboding, and all the songs are at least as hypnotizing as the songs in EDS. It's kind of a stretch, but you might like it. ( http://www.youtube.com/watch?v=44uq4VsIEP8&feature=related
VNV Nation - Praise the Fallen - Once again, this is rather unlike EDS and it certainly isn't dark ambient. I do kindave identify EDS with it because they are both electronic music that is dark and aggressive. Songs on it stride the line between synth-pop, techno, industrial, and neo-classical. Any metalhead that gets into electronic music should be able to find value in this if they get past the "inferior" pop-ish elements. ( http://www.youtube.com/watch?v=HxLY2x7bEvs
That should be quite a bit to chew off, you know, rather than a list of 10 obscure bands with 2 hour long albums you've never heard of with no explanations whatsoever.
