Here is a never before seen 7 minute version of Jason Crest's seminal composition, Black Mass, which I have discovered on a cancelled 10 inch Philips metal acetate.
Whilst sounding essentially the same as the single release, the mix is different, brighter sound, cleaner, more dynamic, with different introduction and ending.
I have no idea why it was cancelled, and Jason Crest themselves are apparently unaware of this recording being made.
