There's not that many these days who travel for a soul night full stop, not a great distance antyway. Anyone who does is often travelling to a niter after.
Most local soul nights don't have a market for so called big name dj's as most "locals" no longer travel any great distance, and I would guess most local punters don't really give two hoots who plays what judging by playlists and demand for certain records all the time.
There's not many soul nights I would travel for. Lowton, Orwell & Piercebridge are some that I would and do travel to, Union when it was going but that was hardly travelling for me But having said that if I'm going to travel I want something other than the same old same, I can stop local for that.
