During this EF this topic came up a few times during conversations, so here are some thoughts about it: right now Main Stage music is a mix of house and techno ranging from softer variants to somewhat harder beats. The main argument against the inclusion of Industrial, EBM, Dark Wave etc. is that it wouldn't fit with the rest of what is played and that it wouldn't be Fursuit friendly. I am not so sure about that, because the line between the standard club hits currently employed (Aquagen, Swedish House Mafia, various hard style remixes of 90's club hits etc.) and club hits from the "dark" scene is very thin, and usually rather fluid. I mean, it's not as if it suddenly were completely different music. Sure, there are some focus shifts in melody and beat, but not to a degree that would make it impossible to dance to.
So my suggestion is this: if a special SIG cant be done because of licensing issues, why not integrate some selected club songs from the dark scene into the main dance events, so there is something for everyone to enjoy and dance to? I am sure we can come up with a list of songs that are very compatible to what is already played. If you can play Aquagen, you can also play Eisenfunk. If you can play hard style techno you can also play Noisuf-X. I'd even say if you take out certain sequences from electro/industrial club hits and mixed them into the usual song setup, you wouldnt even notice the difference.
That's my input for a start. And please, don't get me wrong: this is by no means me saying I don't like what BBF or the other DJs are playing. It is just that I think it is possible to create a main stage dance that pleases both camps in this particular case. Because the music really isnt that different, at least not if you look at the songs where those genres overlap. I can dance to house and techno, but I can dance better to Industrial/Electro. Would it be too much to ask to include something compatible from those genres? I think even those who don't know or like that scene will still be able to dance to it, just like I can dance to their music. Why? Because when it comes down to rhythm, melody and beat, there isn't that much difference after all.
