Well.... tons of Supraphon records.... not in The Netherlands as far as I know, They were cheap, yes, but they had a name of bad quality (like Europa / Karoussel records) and the performances coudn't tip to the Westen musicians. So you don't see them so much, especially not SQ ones.
Melodia was represented by CNR here and had the same problem, although Russian music should be played with Russian musicians, because "only they could feel the spirit" of the composer :) , according to CNR.
Reminds me of a nice promo 7" vinyl record I have somewhere. It has a origami promotion leaf.
I begin to think that maybe the curtain wasn't as iron as accepted history suggests, in some regards.
...The reason I say this is because I myself have wondered about the HMV / Melodiya relationship... companies operating under the respective regimes of these apparent mortal foes were quite happy to allow Soviet product to travel beyond their borders... and sell it to us.
(I used to have an air rifle made in USSR, which, when I came to sell it to a dealer, was told that this was not uncommon at all... "The USSR sells us tons of shit" was the line I remember)
There are quite literally tons of Supraphon records (with English labels!) all over the place when you look in record bins, so they had no problem allowing the Czechoslovakians to sell all they could to us...
...which probably means that western society probably did as much as any Soviet citizen to fund their nuclear armament programme.
Which is a thought that gives you a nice warm glow inside... doesn't it? :)
((I don't remember Maggie or Ronnie complaining at all about this... so maybe I'm wrong))
But I would think that as Supraphon sold to our markets, they would naturally follow suit when Quad albums became the fashion over this way.... but that said, can't say I've ever seen one before, and would imagine yours is something of an anomaly, if not a rarity.
I never saw a quadraphonic vinyl and didn't know they made four channel records behind the Iron Curtain. Or was this only for export purpuses, as seen on the back of the cover GB/GE/FR texts?
