The Wu-Tang Clan certainly know how to pull something spectacular out of the bag. The hip hop collective recorded Once Upon a Time in Shaolin in secret over the course of six years. Instead of leading up to a big release, there was only one copy ever made. It sold for a huge $2 million dollars. 

Once Upon a Time in Shaolin was recorded secretly, and the recording took a total of six years. While it was awaiting auction and sale through Paddle8, a music auction house, it was stored in a secure vault in Marrakech, Morocco at the Royal Mansour Hotel. The album was inspired by Cilvaringz’ research into the Renaissance period of history. 

Interestingly, the band put in a clause: “The seller may legally plan and attempt to execute one heist or caper to steal back (the album), which, if successful, would return all ownership rights to the seller. Said heist or caper can only be undertaken by currently active members of the Wu-Tang Clan and/or actor Bill Murray, with no legal repercussions.”
