In my opinion, labeling techno is not a simple thing to do but I'll give it a go (and I don't want to be considered a purist at all!!).

The stuff wolfgang voigt did on Studio 1 was really wonderful. The 10 releases were edited between 1995 and 1997. Would recommend them for sure.

Again, it is hard to label sub-genres. I prefer to call it "techno made with diferent components, etc etc"
