When I was going out in Edinburgh, around 98-01, the busiest nights were definitely the ones where it was just the residents playing. Nights like Pillbox, Apex, Loop, even Lift only booked a big name once in a while. Pure could do it every time but that was because Pure was Pure and people would go regardless of who was on. Lost / Dogma had it cracked too, but generally the place always struck me as a party city that isn't too bothered about big names, even to the extent where if the residents weren't playing then people wouldn't go down as they wouldn't be entirely sure of what to expect. Maybe that's still the case.
