In the wake of Doug Morris’ arrival as Sony Music Entertainment CEO, RCA Music Group has solidified its executive ranks with the elevation of Peter Edge to CEO and Tom Corson to president-chief operating officer.

Edge, who had been president of A&R since 2007, will report directly to Morris. He will oversee the day-to-day operations of the group and its labels, now comprising RCA, Jive, J and Arista.

Move was widely expected following the departure of former RCA/Jive Label Group chairman-CEO and A&R mover and shaker Barry Weiss for Universal Music Group.

Promotion puts an established A&R leader at the top: Edge has signed or helped develop such acts as Alicia Keys, Dido, Mario and Jamie Foxx. Company’s breakout acts Marsha Ambrosius and Jazmine Sullivan were also his charges.

Corson, whose history with the division dates back to J Records’ inception in 2000, will now helm promotion, marketing, publicity, digital, sales, international, video and operations for RCAMG.

He was most recently exec VP-general manager of the unit. He has taken a leading role in label projects by Kings of Leon, Rod Stewart, Ke$ha, Foo Fighters, Kelly Clarkson, Pitbull and Jennifer Hudson.

Morris said in a statement, “Sony Music is well positioned for success with a deep lineup of many of the most accomplished creative and operational executives in the industry. The enhanced roles for Peter and Tom, who have long played integral roles in the achievements of the RCA labels, underscore that strength. They are the ideal pair to lead the group’s continued development and success moving forward.”
