I really enjoy the Chod cassette, though my favorite part of it is also included on the V/A Life After Fallout / Odland C-60, which is one of my favorite cassette comps from the decade. The howling wolves are set perfectly to the tone and atmosphere of the dark ambiance. That comp brings to mind Advokat Ihrer Hoheit. I've found they are sorely forgotten. I have not heard Exotoendo to compare to Chod.
I have three Batchas full-lengths, and I enjoy them all. The other project, Myiase, was of even more interest. Their track on the V/A Bunker Archeology CD was very good, as was the rest of that compilation.
TGVT, Tuu, and Hybryds...tribal ambient (maybe more aggressive and dark than ethno-ambient, though Tuu is probably better linked to that grouping). By morning, I'm sure there will be others...
