A few years back I was asked why I was playing Cliff Nobles OLIGS on Atlantic at an ovo night as first release was on VJ by an acquittance so no malice intended (I think) Obviously we went through the local / national release thing but he was still objective.
I said if I was to offer you the Ivories on Despenza or Wand which would you want and he said Wand as its so much rarer. He then agreed that both local / national releases are ok to play.
We went on to agree that records made deliberately for the northern scene should not be played at an ovo event UNLESS unreleased like Grapevines Barons Of Soul & Eddie Holman. Were not the soul police so who cares what we came up with.
Yes I run an ovo event but I attend events without worrying what there policy is. So in my opinion some grapevine are ok but not all.
