Got to be subjective this one Ivor.
I can really only suggest names that I think have similar tastes to my own, but I'd certainly nominate a couple of National Heavyweights for starters.
Dave Godin - Impeccable taste and the biggest influence on my own in the early days.
Richard Searling - 70's & 80's He always had a great ear for a quality tune!
Outside of those, the Soul Essence & Pitches guys have always been people I can rely on for a good tip on a quality item.
Names that immediately spring to mind.... Rod Dearlove (How many GREAT tunes has Rod been behind?), Mike Charlton (Absolutely!), Bob & Gavin (Naturally), Steve Plumb (The man behind the best LP only set in the known world), Steve G. Gareth Donovan, (how come, for someone so young?) etc. and in my own direct circle... The Wikipedia of Soul, John Benson (great ears)..... The very wonderful Kevin Briscoe (if you've ever heard him play out or received a CD from Kevin, you'll know what I mean The guy has incredible taste) and my partner in crime Tats who (as you know) has blinding great taste, always uncompromisingly soulful and, these days, one of the most entertaining Real Soul DJ's on the planet.
People who may not DJ a great deal, but I know have great taste (i.e. similar to my own) would include Binsy (He knows the score) Blake Helliwell (Sublime taste in music) Richard Broughton (First Class) Alan Darker (Always a winner!) Rob Hurcombe (Midlands Maestro) Mike Lofthouse & Adam Garbutt (North East Legends) Eddie Hubbard (A1+) and Dave Turner (Arkwright) who is so similar to me, in where we are at in the music, we're thinking of setting up home together .
Oh... and I think you know a good tune, when you hear one, as well Mr Jones .
Sure there's a lot more, but at 11:00pm (and I'm supposed to be preparing a presentation for tomorrow morning) that's just a quick brain dump.
