Interesting — vinyl was scarce in the Soviet Union, so to make records some people stole discarded x-rays from hospital dumpsters, burned music onto them, cut them into a circle with manicure scissors, and burned a hole in the middle with a lit cigarette. The linked website has some great images of these homemade records. It’s called “bone music,” and the practice went on during the late 50s until authorities cracked down. I think I want one.
Many thanks to my former student Penny for alerting me to this story.
