Yeah, I totally get what you are saying.
But in a genral context, the restraints are getting narrower as people focus more and more on sub sub sub sub genre.
The point I`m making is that you can be experimental and still be "average listener/clubber" friendly.

Look at the hip hop world for examples of this.
Even on the real commercial side you had tracks like Kelis` Milkshake, and Missy Elliots Pass tha Dutch, which were by no menas conforming to the rules of commercial hip hop, and they still sold millions and rocked the floor.

The problem comes partly from apparent peer pressure too.

I think people want to fit in, are a little scared by reaction to try new things.
Also there`s a lot of idolatry and emulating of heroes, so aspirations are just to be like someone else rather than to stand apart as an individual.

I`m not saying people should start using morphic time signatures, and full orchestras to make techno, but the total lack of any adventure or attempting to break the norm is a little disapointing.

There doesn`t have to be one or the other, but I think, experimentalism can be used in a more conventional "I just want to rock" context, and those who just want to rock, could do with a bit of experimentalism.
