Wu-Tang Clan are about to become the Indiana Jones' of Hip-Hop. They've spent the last few months on lock down recording a super-secret double album known as Once Upon A Time In Shaolin, but they're only going to sell one copy of it, expecting to be priced in the millions, and even then not until that lone-silver-plated-copy completes a tour of museums, galleries, and festivals.

That will be the only place anyone without deep pockets can hear it. Because Wu-Tang are employing heavy security to make sure no one takes in a recording device to leak it. Speaking in an interview about the concept with Forbes, the album's producer Tarik 'Cilvaring' Azzougarh said : "One leak of this thing nullifies the entire concept'.

RZA also gave his thoughts in the same interview: "We're about to sell an album like nobody else sold it before. We're about to put out a piece of art like nobody else has done in the history of [modern] music. We're making a single-sale collector's item. This is like somebody having the scepter of an Egyptian king."

The album lasts 128-minutes, so you better hope your local gallery/museum has chairs. Wu-Tang Clan are also planning a more traditional record , A Better Tomorrow, set to be released later this year in celebration of the groups 20th anniversary.
