Wu tang Clan release long anticipated single album.

Hidden in a vault in Marrakesh, it has been one of the most highly-anticipated albums in music history.

And tonight, after six years, the Wu-Tang Clan finally opened the handcrafted silver box that holds their unheard record Once Upon A Time In Shaolin - before sealing it away once more.

In an attempt to break free from the Spotify and YouTube era of freely-shared music, rap's most influential collective is selling the 31-track double LP to one bidder for millions of dollars.

After a private online-only sale this month through art dealers Paddle8 - which employs Britain's Princess Eugenie - the buyer cannot share the album for at least 88 years.

DailyMail.com was there with the group's de facto leader RZA, producer Cilvaringz, a small group of prospective buyers and half a dozen selected fans in Queens, New York City, for the first and last time any of the album would be played before the year 2103.culled from dailymail.

While some were fans, others were advisers who hailed from as far as Asia to inspect the 'artwork'.

One adviser for a Chinese collector, who wished to remain anonymous, told DailyMail.com collectors are clamouring to get their hands on the record and its silver box - whether they like Wu-Tang or not.

The box comes inside a cedar wood treasure chest covered with black cow leather and light beige velvet lining.

Inside, is a cinematic-style record, plus a leather-bound 174-page manuscript printed on gilded Fedrigoni Marina parchment with lyrics, credits, tales about the recording.

The adviser said: 'Someone said it would be worth $1 million. That's nothing. This is something completely different; completely new. I don't think I could put a price on it.
