Also, I agree about techno as well, though IMO techno is really the same as house music, just usually a little bit faster. Think about it this way: what is the substantial difference between a record released on Relief out of Chicago and a techno record? there is basically none! And of course you have old D. May mixes from the Music Institute that were largely house and C2’s mix for “Kings of Techno” which was a mix of disco and electro and new wave, the same things that influenced house. It all works together….

“Back then, the purpose was to capture and define this red-hot, soulfully thought out music that was coming from the black urban mind.”
“I never wanted to call it techno…. I felt that to call it techno was too generic.”

And he was right, over time what’s generally perceived of as techno has become more and more generic in defintion of what should be techno (must be banGin’, must be 4×4, must be dark and moody, etc. etc.) and, as tom said, subdivided into tighly constrained sub-genres i.e. this contemporary Minimal scene and previously the compressed loopy bullshit from the mid to late 90s, while all the time there’s still red-hot soulful electronic music not getting the same dues because it doesn’t quite fit in with the major scene of the day.
