From the 1930s-60s, vinyl was too expensive in the Soviet Union, so bootleggers began using X-ray plates to print records. The useless X-rays could be purchased from hospitals for very little, and were thick enough to retain an impression that could be played on a phonograph.
The quality wasn’t great, but the price was right, and these presses let people in the Soviet Union hear banned music, like Jazz and early Rock ‘n’ Roll. Romantic.
