Have y'all ever heard of Bone Music or Rib Music?

Long story short, during the Soviet Union in the 1950s, 60s, and into the 70s, there was a ban on a lot of music, especially stuff coming from the West. And so people would try to copy them and bring them in, but they ran out of vinyl to do bootleg records with. But they found out that the polyester film that the X-rays were done on could be turned into a record for a few plays anyways. It wouldn't last very long, but you could get, I think it was like 10 or more plays out of it, and that would last at least that long. So it was a way of recording and distributing music underground all over the Soviet Union. And because the majority of them were on X-rays that had been taken of bones and skulls and all that, it became known as bone music or rib music. I first came across this when I was taking Russian as a student back in 1989 or 98, one of those two years. And my teacher, who had lived in Russia for a long time during the Soviet Union, had actually brought that up when she talked about records on X-ray film. And I was like, what are you talking about? And so she gave me an explanation of it, and I didn't think anything of it until about 10 years ago, I think, or more, NPR did a story on it, and then it reminded me of that. But it's a really fascinating glimpse into the Iron Curtain to see that people were recording and distributing illegal music because there was such a demand for it. And it's a really cool part of history.
