The sole copy of the Wu-Tang Clan's album "Once Upon a Time in Shaolin" has been put up for auction by its owner, businessman Martin Shkreli.
The controversial former pharmaceutical executive Shkreli bought the only copy of the record from the rap collective in an auction for $2 million in 2015.
However, they donated the proceeds of the sale to the charity after discovering the buyer was Shkreli as they objected to his business practices.
On Wednesday, Shkreli listed the album on the online auction website eBay, with a message criticising the Gravel Pit rappers.
"I decided to purchase this album as a gift to the Wu-Tang Clan for their tremendous musical output," he wrote in his listing. "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. I will be curious to see if the world values music nearly as much as I have."
Shkreli also wrote that he would donate half the proceeds of the sale to medical research but that he may cancel the auction and destroy the album "at any time".
As of Thursday morning, the top bid for the record was just under $1 million.
The 34-year-old earned notoriety after raising the price of AIDS medication from $13.50 to $750 per pill. He was convicted of two counts of securities fraud in an unrelated case last month.
During jury selection for the fraud trial, one potential juror was excused from duty after admitting he was prejudiced against Shkreli as he had "disrespected the Wu-Tang Clan."
The disgraced businessman promised to play the album in full if Donald Trump won last year's U.S. presidential election, but only previewed the introduction and one track online after Trump's victory.
