Not sure if this is the correct place to post this:
I'm trying to find a track I heard also in the 90s, so would have been from early 90s - 1997 at the latest. It was instrumental with a female vocal saying 'woooh' in slowly descending pitches repeatedly - there was a breakbeat in the background which paused briefly after every few bars and some filtered keyboard arpeggios. That's about all I remember. I seemed quite long and was very chilled.
I had it on a tape of 'Flying High' by Mixmaster Morris that a colleague gave me and this was at the end of that tape - I thought it was part of that album but it wasn't, although it's definitely in a similar vibe.
It's quite obscure - I hadn't heard it before and haven't heard it since. I think it was quite a long track, and could have been a live mix. It's certainly not anything from any of the obvious ambient, dub, breakbeat compilations from around that time..

Any help would be hugely appreciated - I remember it as being one of the best pieces of music i've ever heard and am amazed I've never heard it since, but of course I could be listening through rose tinted ears (if you'll pardon the stretched metaphor).
