The Wu-Tang Clan have been working on a secret double LP

In the midst of this, the New York based group have been working on a new unknown project, a double-album called, 'Once Upon a Time in Shaolin,' which They have been working on in secret for the past six years.

But astoundingly Wu-Tang Clan only plan on releasing one copy of it.

In a new interview with Forbes one of the group's original members, RZA, are going to sell just one copy of the 31-track double LP.

"We're about to sell an album like nobody else sold it before," the rapper explained. "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."

Their aim is simple, make music be considered as art, but before the previously unknown studio set is sold, it will "tour" through museums, galleries and festivals, but will use headphones to project against piracy.

On the new secret album's official website, the group have shared some specific details of what it will contain. 'Once Upon a Time in Shaolin' will feature "special guest appearances" including FC Barcelona soccer players and "a unique tapestry of guest performers."

The rap group's aim is to make music be reconsidered as art

"The music industry is in crisis," the band wrote. "Creativity has become disposable and value has been stripped out. Mass production and content saturation have devalued both our experience of music and our ability to establish its value. Industrial production and digital reproduction have failed. The intrinsic value of music has been reduced to zero. Contemporary art is worth millions by virtue of its exclusivity. This album is a piece of contemporary art."

No official dates for the album's tour have been announced.
