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.
Was this a proposed EP for release in 17th January 1967? This 10 inch Fontana acetate brings together all tracks from their 2 singles with the 'Atmospher' choice. It is listed as an EP on the label. 'Atmospheres' is shortened, slightly different mix.
There are severals sites carrying the band's history, but briefly, from Mersyside (as Four Just Men) moved to Manchester as Wimple Winch (Stockport area) disbanding in 1967.
