Sony Music Nashville will announce Gary Overton as its new CEO this afternoon, sources tell Billboard.biz.

Overton, currently EMI Music Publishing Nashville's executive VP and GM, will replace Joe Galante, who announced yesterday that he is exiting his position of chairman of Sony Music Nashville. Galante is expected to assist during a transition period.

In turn, Ben Vaughn will be tapped to lead EMI Music Publishing Nashville, replacing Overton. Vaughn was previously VP of writer and artist development and will be named executive VP and GM. He'll report to EMI Music Publishing chairman and CEO Roger Faxon.
