There are a lot of collectable pieces of music memorabilia out there. Bands all the time nowadays release limited-edition versions of albums, though this is often something of a cynical marketing ploy more than anything else, if truth be told. Some bands release entirely limited singles, and a couple even release strictly limited albums. Few, though, have gone as far as Jean-Michele Jarre in doing this. His fourth album, Music For Supermarkets, only ever had one copy pressed, and this was auctioned off for charity. The master was burnt, and since then, there has only ever been one public playing of the record in its entirety: on radio luxembourg.
