It took me a second after clicking the link Whet sent me this morning to figure out what I was looking at–a record cut into a used piece of X-ray film. Known as “ribs” or “bones”–“roentgenizdat” if you’re nasty–the bootlegs were a crucial part of underground rock ‘n’ roll culture throughout Cold War Eastern Europe. X-ray plates were used because they were cheap to buy in bulk and took a groove OK, although records made that way reportedly had inferior sound quality and wore out in a few months. Still, you have to imagine that the people buying these things got off on the macabre visual effect.
