Yeah, that`s the whole point here.
A lot of techno producers just make the same sound, over and over again.
Particularly a lot of the new kids, who are just emulating their heroes.

I try to approach music without any labels at all. I call everything I make techno, because for me, techno is progressive electronic music.

Breaks, Dark, Housey stuff, industrial stuff, commercial and trancey, whatever.

How can anyone stick to the same sound, and the same format again and again and again, I just don`t get it.

It is a small genre if you are just making and sticking to one tiny niche within it, but for me it is a music with no boundary.

Producers in techno who are diverse for me would be.

Underworld
and erm.
Innigo Kennedy
Marco Corola
even Marco Bailey tries new stuff.
Samuel L Sessions

erm other than that I can`t think of any, that`s not to say there aren`t that many.
