Rayna Bass and Selim Bouab will remain as co-presidents of 300 Entertainment, while Nicholas Ziangas and Molly McLachlan have been promoted to co-presidents of 10K Projects. The announcement says that more announcements will be made shortly, and does not include leadership for Elektra Records, except to say that former president Gregg Nadel will be moving to a new role within the Warner Music Group.

“Atlantic Music Group is home to the most extraordinary artists and executives in the world,” Grainge said in a statement. “This great label has moved through a meaningful transition, and emerged with a world-class team, made up of ambitious innovators and veteran visionaries. We have a plan to build on the extraordinary achievements of the last twenty years, honor the independent DNA of our labels, and collaborate with artists to pioneer a future filled with opportunity. To all our artists, managers, and partners, we are committed to a single principle — maximum impact for original artists. We’re looking forward to doing big, bold, brave things together.”

The announcement of the new structure follows an announcement last week about a reorganization of the Atlantic Music Group, through which several key leaders at Atlantic, 300 and Elektra departed the company, with layoffs of some 150-175 employees. That process is said to have been completed last week. Additionally, today’s announcement confirmed that 10K will continue as a standalone label under AMG, while Elektra, Fueled By Ramen and Roadrunner will continue as imprints.

“AMG will be lean, agile, fiercely creative, and deeply passionate about artists and their fans,” Warner Music Group CEO Robert Kyncl said in a statement. “We’re opening an exciting new chapter in the story of an iconic label. Elliot’s thoughtfully chosen a team that combines a wealth of experience, a diversity of expertise, and a commitment to excellence.”
