Joel Mull prog techno!?!?! i haven't been keeping up with the man the past little while, but his history is straight up Swedish-Code Red- killah drum loops kinda sound. But give me some recent track titles of his and i'll have a hear-see for myself...
To answer Coleridge's original question... First off, I think you're correct in that there's definitely music there that deserves to be called 'prog tech'. But there could be a lot of different answers to why so called 'tech heads' don't welcome the term 'prog-tech' even though it is fitting. I'll try to answer it from a personal point of view.
First, for me so called 'prog tech' sucks the big one. I actually find it worse than 'euphoric trance' or even 'real' progessive house. It attempts to capture the feel of techno... and in doing so it definitely captures the timbre of it. But it lacks the incredible rhythm that all good techno has. Prog tech sounds like slowed down techno that plods on, and on and on... it doesn't help that prog djs for the most part enjoy playing their tracks out until the very end. So attaching the moniker 'tech' to something i hate, when tech implies something i love (ie. pounding, kill yo' momma techno) is something i'm naturally opposed to. Progressive breaks could be a different story, i actually like progressive breaks and i think most breaks headz do to... so therefore they're more likely to accept the moniker.
Second, theres the whole 'techno has to be underground' stuff. Prog house is incredibly popular and therefore commercial (and for the life of me i can't figure out why...) where as the tradition in techno is something completely different. It has UR, Detroit, slum parties in Berlin and all that business... so the two genres don't mix in that respect either.
Third, a percentage of techno jocks tend to be tightwads that have revile anything besides from techno. This minority tends to be quite vocal though... so it could seem that the techno community rejects the moniker 'prog tech' while in fact its just that small percentage is making a lot of negative noise ... where as the majority is down wit' it.
my 2 cents
