In the Soviet-era, western music was banned and vinyl was scarce, so ingenious Russians began recording banned bootlegged jazz, boogie woogie and rock 'n' roll on exposed X-ray film salvaged from hospital waste bins and archives. Censorship is a pain but it's always fuel for creativity.
"Usually it was the Western music they wanted to copy. Before the tape recorders they used the X-ray film of bones and recorded music on the bones, bone music."
"They would cut the X-ray into a crude circle with manicure scissors and use a cigarette to burn a hole. You'd have Elvis on the lungs, Duke Ellington on Aunt Masha's brain scan — forbidden Western music captured on the interiors of Soviet citizens."
