back in the day..certainly when i was doing the allniters etc..very few if any unreleased tunes were on the decks or playlists.Since of course, many top sounds have been unearthed.So which stand out for you?..criteria being unreleased at the time (of recent recording or generally at that time) these mainly being the ones that have lain in archives or vaults or produced as limited acetates, tests, not demos that were pressed to precede an intended release. Many now appear on CD to supplement existing recordings and of course the Kent label has unearthed some great stuff.
one of my faves is Maurice Williams-'Look my way' which appeared as an LP only on Kent. So be it northern,crossover,or deep..or whatever whats a really worthy tune thats eventually seen the light of day?
