The physical action of mixing on CD, or twiddling vinyl, or moving sliders when using a laptop, is hardly much different is it.
Lets face it, Dance music performers aren`t interesting to watch, lets not kid ourselves, it`s some guy, or girl, fiddling with some very unphysical equipment, making small movements (unless it`s some gimp scratching records with his nose or something).
So all this "Vinyl is a better performance" is just sentiment.
You can put the same amount of energy into whatever you are using to perform with.
Be it a mouth organ, or a CDJ.
Mark for instance, will always be the jumping, arm flailing, gurning loon, he is, no matter what he uses. And that`s what people love.
The music is paramount, it`s 2007 and we need to stop talking about the medium, and start talking about the music, and it`s future.
