Chairman and chief executive Tom Whalley is leaving the company after a nine-year run and is being replaced by an executive team led by top-selling producer Rob Cavallo. The announcement was made Tuesday.

Cavallo, who brought artists including Goo Goo Dolls and Green Day to Warner Bros., becomes chairman of the label after serving as chief creative officer of all of Warner Music.

Todd Moscowitz, who now heads Warner’s independent label group and Asylum Records, becomes co-president and chief executive officer.

Atlantic Records general manager Livia Tortella becomes co-president and chief operating officer. Tortella brings with her a track record of growing digital sales at Atlantic, which became the first label to have greater digital revenues than physical sales in the U.S. in 2008.

Diarmuid Quinn is stepping down from his position as chief operating officer.
