i think music has become too pigeon holed. Too many producers releasing the same sound over and over...
diverse eps is a great idea.
unfortunately its the same with most nights out. warm up dj plays the same as the main dj. it can get really boring.

This is a problem with techno at the moment I think, cause I do go to other gigs where there is a nice mash up (usually resulting in end of night breakcore!).
