Industry speculation that Michael Cohl is out as chairman of the board for Live Nation is premature, but it's apparent that there is plenty of discord atop the world's largest concert promotion company.

Even if he remains in place for now, some sources indicate that Cohl's departure from Live Nation is imminent.

Cohl, Live Nation's largest shareholder, had been chairman of the company since February, and prior to that was vice chairman since 2006. As of now, he remains in that post of chairman, and also is CEO of Live Nation Artists, the division of the company that orchestrates the much-publicized deals with such artists as Madonna, Jay-Z, and U2. These Madonna and Jay-Z deals alone have been valued at $120 million and $150 million, respectively.

Sources say these deals and how Live Nation will pursue them going forward is the root of the tension in the Live Nation board room. Sources say Cohl and Live Nation CEO Michael Rapino differ on how aggressively to pursue acquiring new artist deals, as well as how many and what kinds of artists to sign. As CEO of Live Nation Artists, Cohl reports to Rapino.

However, according to sources, Live Nation will continue to pursue multi-rights deal, with a Shakira deal believed to be next in the pipeline. Cohl, known for pioneering a global touring model that taps into numerous revenue streams, has promoted every Rolling Stones tour since 1989, including A Bigger Bang in 2005-2007, the top grossing tour of all time at $558 million. Cohl has more than eight years left on his non-compete with Live Nation from when he sold his company CPI to Live Nation in 2006, and has no contractual right to buy back CPI.

Live Nation declined to comment for this story.
