The music industry may have a bit of life left in it after all. At least that’s the impression one is left with this week after Citigroup scored a better-than-expected $4.1 billion from two deals that mark the end of a months-long auction to sell off the parts of 114-year-old British music company EMI Group.

Vivendi’s Universal Music Group and Sony won the auction for EMI’s recorded music and music publishing operations, trumping bids by archrivals Warner Music Group and BMG Music Publishing at the 11th hour, reports Peter Lauria, editor-in-charge of Technology, Media and Telecommunications at Reuters. Universal plans to buy EMI’s recorded-music unit for $1.9 billion, according to a source involved in the process, snagging the rights to music by artists such as Coldplay, the Beatles and Katy Perry in the deal.  A consortia led by Sony is expected to buy EMI’s publishing operation for $2.2 billion.

MF Global’s liquidators are struggling to sell the Asian business as one concern because of problems unwinding trading positions, so they may now sell the various country units separately, report Reuters correspondents Rachel Armstrong and Bruce Hextall.

Japan’s Olympus admitted it hid losses on securities investments dating back two decades, bowing to weeks of pressure to explain a series of baffling transactions that have put the future of the firm in doubt.

The dark and sometimes dangerous triad of ties among gangsters, businesses and politicians has a long tradition in Japan, which helps explain why a scandal engulfing Olympus has stirred up media and market talk of possible yakuza links, despite company denials and a lack of evidence.

When is a merger-of-equals really a takeover? One easy way to tell is when the top brass get rich and undeserved paydays. There’s probably no better live example than the just-delayed sale of Massachusetts electric utility NSTAR, reports Breakingviews columnist Rob Cox.

Although the size of MF Global’s wager on European sovereign debt has received a great deal of scrutiny, the accounting and the disclosure surrounding it have not–and may have played a role in the firm’s demise, writes Vanity Fair’s contributing editor Bethany McLean.

“The tragic element of Corzine’s MF Global is that Monday’s bankruptcy filing could have easily been avoided if Corzine’s ego and ambition had been held in check by someone — anyone — willing to stand up to the former New Jersey governor, senator and senior partner at Goldman Sachs,” reports Bloomberg.

The ex-CEO of Japan’s Olympus Corp said he wanted to meet investigators appointed to probe a scandal engulfing the firm, but added it would not be safe for him to travel to Japan.

Michael Woodford asked too many questions. That’s the reason the 51-year-old Englishman gives for why he lost his job as the first-ever foreign-born CEO at Japanese camera maker Olympus a mere two weeks after he was given the role in early October.

Woodford tells Reuters investigative reporters Kirstin Ridley and Alexander Smith in a new special report that it was his inquiries into a series of questionable takeover deals and advisor payouts the company made over the past half decade, including the biggest mergers and acquisitions fee ever, that led to his ouster. Board members insist instead it was Woodford’s failure to grasp the company’s management style and Japanese culture that cost him the job, but Woodford says allegations of a “power grab” by him are not the “real story”. Now, Woodford is on a one-man campaign to “cleanse” Olympus with the goal of removing its entire board.

Giving in to pressure from many corners, Olympus on Tuesday named six men, including a former Japanese supreme court justice, to investigate the past M&A deals at the core of the scandal in a bid to stem an exodus of irate investors. The all-Japanese committee will look into $687 million in payments made to a financial adviser for the $2 billion purchase of British medical equipment maker Gyrus in 2008  and the acquisition of three companies in Japan that Olympus, under chairman Tsuyoshi Kikukawa’s decade-long reign at the company, later largely wrote off.
