Producer Rubin in "partnership" with Columbia

NEW YORK (Billboard) - Rick Rubin's long-rumored move to Columbia Records is now official, although there are no details yet on what the Grammy-winning producer's exact role will be at the label or where he will be based

The label released a statement Monday confirming the Rubin hire and stating that he would "form a dynamic and creative executive partnership" with Columbia chairman Steve Barnett, under a new model devised by Sony Music Label Group president Rob Stringer.

As part of the deal, the Los Angeles-based mogul will bring his American Recordings label to Columbia, which previously distributed the imprint in the late '90s and early '00s. American, which for the last year-plus has been distributed by Warner Music Group, has a roster that includes Slayer, Dan Wilson and (International) Noise Conspiracy. It also controls catalog from Johnny Cash, the Black Crowes, Danzig and the Jayhawks.

As expected, in addition to producing albums for Sony BMG acts, Rubin will continue his producing activities for artists at other major labels. In this capacity he will work with artists signed to Warner Bros., including Linkin Park and Metallica.

Rubin won five Grammys in February for his work with the likes of the Dixie Chicks and Red Hot Chili Peppers.
