I haven't been following this, so apologies if I cover old ground with any comments.
I understand very well the "rules" the scene tries to implement in this respect, and pretty much agree with them. I certainly have my own standards on the rare occasion I'm asked to play at such an event (though reserve the right to use my CD-R's if I think the equipment is shite!).
However, I do think the scene needs to look inwardly now and again and question it's motives etc. Even if it means nothing changes, it pays to view things with an open mind. When doing so, many searching and thought provoking questions come to mind, so it's worth doing so just to "check" yourself.
As such, do promoters who hold the view that OVO is paramount thrust themselves forward to pay their DJ's the kind of fee that is commensurate with collecting rare vinyl.........whatever fee might be deemed appropriate...........certainly more than their petrol money!! I doubt it.......but OVO is SOOOO important!
