Some recent listens:
O Yuki Conjugate: Peyote
I like this better than the last time I played it, but still prefer Equator or the earlier stuff. "Tribal" ambient with a lot of percussive elements. It's a good album, just overshadowed by their other stuff.
Gnawed/Ligature Impression - Split
Gnawed is great as always, LI is very average PE.
Shibalba - Samsara
Not exactly dark ambient because it's too busy. Some percussive elements, ISN-style synth orchestrations, and a general "ritual feel". Pretty good but needs more time to sink in.
Mental Destruction - When Madness Strikes
Primitive as all hell industrial, basically on par with Nekrophile type stuff in terms of fidelity. It works though, highly enjoyable. I wish they would release new material or at least reissue the back catalog with some bonus material.
Macronympha - Super Oxide
Studio material from '90-93 compiled and released in 2011. Some good harsh noise, junk metal in there as well. Not a truly great release but good and a worthwhile listen.
Bad Sector - Cephus
Filed this away after buying it, thought it wasn't as good as past material. Played again recently and changed my mind. This is excellent, just need to play it more often.
