This is a tape recording from around 1995/1996 from Annie Nightingale's Chillout Zone on Radio 1. Never found out what it was, and it has haunted me to this day. It is basically a slow and melodic tune with a soothing female voice giving it a relaxation tape theme.
You superstar. Thanks for the ID, and double thanks for the mp3.
Who'd have thought ... a Danny Rampling remix too ... I'm still in shock that he had his hands on this little gem.
