Wu-Tang Clan began working on Once Upon a Time in Shaolin in the late 2000s with producer Cilvaringz. In July 2021, the US Department of Justice sold it to non-fungible token collectors PleasrDAO for $4 million to cover Shkreli's debts PleasrDAO said they hoped to make it more widely accessible. In March 2018, following Shkreli's conviction for securities fraud, a federal court seized assets belonging to him, including Once Upon a Time in Shaolin.

The winning bidder was Martin Shkreli, the CEO of Turing Pharmaceuticals, who paid a reported $2 million. A legal agreement with the purchaser stipulated that the album cannot be commercially exploited until 2103, although it can be played at listening parties. A single two-CD copy was pressed in 2014 and stored in a secured vault at the Royal Mansour Hotel in Marrakech, Morocco, then auctioned through auction house Paddle8 in 2015. The album was recorded in secret over six years. It was limited to a single copy sold in 2015, and is the most expensive work of music ever sold.

Once Upon a Time in Shaolin is the seventh studio album by the American hip hop group Wu-Tang Clan.
