For me, the best Techno has always gone around the houses and incorporated wildly different sounds.
Basic Channel brought dub into the mix. Tim Wright brought in two-step rhythms. CJ Bolland flirts with trance. T Raumschmiere has a punk edge. You can pull all of these elements and more into a Techno mix and create something cohesive, varied and unique all at the same time.
Dubstep is just another element for this.
