Post here some tracks that perfectly fits to your definition of pure techno.
You can also be more precise by specifying a time interval of the track.
There are a lot of styles, but when I refer to techno I usually think about acidic sounds, minimally-structured typical techno rhythm tracks. I'm not that good at describing, and unfortunately I don't know any track that can fit my idea of pure techno. I've heard a lot of pure techno in my life but I've never been able to find tracks names lol. I've heard a lot of live pure techno, also.
Pure techno is kinda anonymous. You can't listen to pure techno and say "looks like a Robert Hood track" or "sounds like a Jeff Mills track". No. Unless you know who made the track.
What do you think? Does the abstract idea of techno exist in track-form?
Lately when I want to listen to some pure techno, I put on the album 'A Sensible Alternative to Emotion' by Exium. The entire album has a pretty consistent sound, so I won't suggest just one track. Another album that is pure techno to me is 'Univrs' by Alva Noto.
