American hip hop group Wu-Tang Clan recently made the news by producing the most expensive album ever made-- but few reports mention the album comes complete with a pair of bespoke speakers from British audio maker PMC.

A mystery collector paid an undisclosed sum reaching the millions for the album, a strict one-off with no other physical or digital duplicates in existence. Titled "Once Upon a Time in Shaolin," it was sold on the condition no content or artwork will be released to the rest of the world for a period of 88 years.

In order to enjoy to be enjoyed the way the Wu Tang Clan intended the album includes the aforementioned pair of hand-built MB2-XBD studio speakers. Each unit is 1.8m tall, carries two 12-inch diameter woofers and pushes 2000W of power, allowing the listener to "experience the audio exactly as its producers intended."

The album, a 128-minute retrospective with contributions by all entire surviving group members, was recorded and mixed on the same model of PMC speakers. To further justify the asking price it is presented in a hand-carved nickel-silver box, and the package includes a leather-encased 174-page book printed on gilded parchment.

"In order to curate the experience of "Once Upon a Time in Shaolin" for the collector, we decided to have two PMC MB2-XBD speakers included with the album," producer Robert "RZA" Diggs says. "These speakers were used during production and mastering and distil this work into its purest form, and in sculpting each beat, each frequency and each flash of feeling, they are themselves a work of artistry."

PMC has a history in the music industry-- after all, it has a client list including the likes of Prince, Elbow, Stevie Wonder, Coldplay, Capitol Studios and the BBC.
