loaded topic could be , heres one, that really annoys the titers off me, the promoters put themselves on at the main time and the guest early fine if you are up and coming or a beginner, but for an established DJ, thats an insult, so obvious that the event they are promoting is about themselves.so the answer is that A FEW people run nites, because they cant get a spot anywhere else.but in general, the venues that I have visited mostly do it for the love of the music, and Holmes chapel is a perfect example, , run by Martyn and Kev, you never actually see there names in the lineup.
