not strictly true mate
the dj and his technique and his programming skills on the night
will set a track in perfect context ( hopefully! ) so the punters get the most from it
it isn't just a case of stick anything on and hope it's ok.
or a case of completely submitting to the track you are playing either
some tracks ONLY come to life when you get stuck in and dj/mix them properly
get them wrong and they suck
how does that work?
Bingo.
Techno can be dull as anything when it's unmixed.
It's definitely a style where the difference between a good DJ and a bad DJ is much more pronounced.
