Jean-Michel Jarre "Music For Supermarkets" (partially lost original recording; 1983)
In 1983, an electronic musician named Jean-Michel Jarre was asked to compose some music for an art exhibition based on supermarkets. He agreed and created Music for Supermarkets in 1983. Only one copy of the album was made, which was auctioned after the art exhibition had ended. To make sure that no other copies of the album would be made the master tapes and plates were burned in front of the attendees.  The reason behind this was that Jarre thought that music is art, and like paintings, it should be treated as such. 
The current owner and their location are both unknown as of the time of writing this.
Before the auction, however, Jarre decided to broadcast the audio via radio, incidentally allowing for the creation of bootlegs. However, the station played in only broadcasted via AM, meaning that any recorded audio was in very low quality.
