Rodders - myself and a few mates are also thinking of doing a night in Wolvo...bit o' house, funk and breaks for those in the know!...good luck with it! We're keeping it small - 200 people max - just for the fun really...and because Wolverhampton has become obssessed with UK Garage and pop R n B.
Best site for tunes is Juno Records: www.juno.co.uk
Dont be deceived by the simple look of the graphics - they've kept it simple and concentrated on the content. Massive selection of current stuff, loads of promos (you have to be hawk-eyed to find these,) and good back catalogue. Prices are competitive considering the massive selection, and I've always received next day/day after.
City Sounds www.city-sounds.co.uk
is good for House promos - mostly Jazz/funky stuff - they do a good newsletter to keep updated on the new imports etc, but no online listening.
Replay are supposed to be OK, although i've no experience.
Forget mailing lists - every f***er has tried to blag their way onto these - labels normally choose the targets to send to - no profile, no toons.
