The business executive and former hedge fund manager took to eBay on Tuesday to sell the legendary rap collective's sole copy of "Once Upon a Time in Shaolin."
"I decided to purchase this album as a gift to the Wu-Tang Clan for their tremendous musical output. Instead I received scorn from at least one of their (least-intelligent) members, and the world at large failed to see my purpose of putting a serious value behind music," he said Tuesday on eBay.
That's no doubt a reference to Wu-Tang's Ghostface Killah, who engaged in a public and often hilarious war of words with Shkreli over his business reputation.
The feud between Ghostface Killah and Shkreli began with name-calling and memes but soon escalated. Referencing the price-gouging scandal, the rapper called Shkreli "a real killer, but you're a soft killer," and introduced his "goons" -- his sister and mother -- to give Shekreli a sharp dressing down.
Shkreli responded by calling Ghostface "son" and saying he'd smack him. He also threatened to erase the rhymesmith's verses from the "Shaolin" album.
The cachet of 'Shaolin'
The sole copy of the 31-track album would come in a hand-carved box with a 174-page leather-bound book of parchment paper containing lyrics and a backstory. It would be sold to the highest bidder.
RZA had initially wanted to forbid the buyer from publicly releasing the album for 88 years but eventually loosened the terms to ensure that it was never sold commercially.
"Shaolin" drew interest from "private collectors, trophy hunters, millionaires, billionaires, unknown folks, publicly known folks, businesses, companies with commercial intent, young, old," RZA boasted.
It was 21 months before Bloomberg Businessweek announced the auction's $2 million winner. The news came beneath a graphic calling Shkreli "young dirty bastard," a reference to deceased Wu-Tang member Ol' Dirty Bastard.
Shkreli, already in the running for most-hated man in America, immediately faced a new onslaught of derision. Even RZA seemed to distance himself from the young mogul.
