hmm, good points @m and I totally see where you're coming from. I wouldn't call myself a techno purist, although I do prefer a lot of purist techno to some of the other shades in the techno spectrum. I see purist techno as more of a hommage to the detroit sound - not necessarily by detroit artists but possesing that original spirit - than a preference towards the academic european stuff that is most often associated with purist techno.
I lump music by people with styles a varied as Juan Atkins, Derrick May, Justin Berkovi, Maurizio, Thomas Brinkmann, Hawtin, Speedy J, Aux 88, Adult, Rob Hood, Lekebusch, Kit Clayton, Laurnet Garnier, and b12 into the purist catagory. Lots of room to travel, and no sign of an impending end to innovation.
I'm not aginst checking everything out and I'll listen to anything that catches my ear, I just find that more often than not the music I end up putting on falls into the purist techno camp.
<-Not a techno purist. Actually listening to some post rock right now.
