Many years later I tracked down the track, it's called "Manège" and is performed by "Lasry-Bachet Structures Sonores". These experimental Musicians wrote and performed music on a series of instruments of their own invention called "Sound Sculptures".
I became hooked on the haunting, other worldly quality of their music....nothing else sounds like it because no one else plays the same instruments (many of which only exist as a single instrument).
Trouble is that most of the music is only available on obscure pieces of Vinyl (including some lovely 10" releases on the French BAM label).
In my role as owner of Egress UK Record Label I took it upon myself to try and get in contact with the musicians and inventors and see if there was any chance of licensing any material for a retrospective CD/Vinyl release.
Well after several months of being pushed from one person to another and ending up down countless dead ends the project came to nothing (this is the usual story when trying to licence obscure old material unfortunately). I may well have another stab at it one of these days as I'd love to try and get hold of the original master tapes and do a proper, fully remastered release.
You can read loads more about the "Sculpture Sonores" here and there is plenty more info dotted around the place (it helps if you can read French though)
My reason for this post is that I received an e-mail out of the blue from someone who had been on a quest to find the "Picture Box" music and they had stumbled upon some of my old forum posts about the subject. They asked if I had a high quality version of the track "Manège" as the only version floating around online is taken from a poor quality YouTube video of the original TV series opening sequence (worth watching just for that hypnotic spinning box!).
Anyway, this inspired me to spend most of today doing a recording from the original vinyl (Structures Sonores Lasry Baschet No.4 on 10" Vinyl BAM LD 098).
I've recorded it at High Res (96KHz 24Bit) and also scanned the cover and labels. The vinyl is not in the greatest of condition and even after a quick spin on the Okki Nokki cleaning machine it still has it's fair share of snap, crackle and pop I'm afraid.
I've spent a little time getting rid of the worst of the crackling, etc. and also applied some light "remastering" as the original recordings are quite muddy, just some very subtle EQ'ing.
The link to the 96/24 FLAC file is in the comments and I'd love to hear your thoughts and ruminations.
EDIT: By popular demand I've added a link to a 320 MP3 Version though I'd strongly recommend you go for the High Res FLAC version if you have the Bandwidth/Time/Patience.
