Denis Balibouse/Reuters If the Wu-Tang Clan's RZA gets his way, you’ll probably never hear the rap group’s latest album, Once Upon a Time in Shaolin. The sole extant recording of its 31 tracks sits locked away in a hand-carved nickel and silver container inside a cedar box swathed in black cow leather in Morocco, waiting to be sold off by the auction house of Damien Hirst and David LaChapelle for a minimum bid of $5 million.
