Agreed, when I did "Soulful" in Bournemouth for Jason Desmond many years ago, he was the the first promoter I'd seen bring his own stylii to a gig (it was in house equipment at the club) and I was really impressed that he seemed to care so much.
To be brutally honest, in this particular respect some people should not be promoting events where rare/antique records are involved. Not doing it correctly is completely disrespectful......and in fact unacceptable when they are trousering £££'s!!
It's also an irony that a scene where the records are so exspensive to buy pays amongst the lowest DJ wages out there. I can understand people doing it as they love it and would buy the tunes come-what-may (wouldn't they??), but not when it's ruining your vinyl surely.........
