Once Upon a Time in Shaolin... is a double album by the New York hip hop group Wu-Tang Clan which was limited to a single copy sold in 2015. One double-CD of the album, which was recorded in secret over six years, was pressed in 2014 and stored in a secured vault at the Royal Mansour Hotel in Marrakech, Morocco. The album was auctioned to the highest bidder through auction house Paddle8 in 2015. A legal agreement with the purchaser states it cannot be commercially exploited until 2103, although it can be released for free or played during listening parties.
