IB tease: Grubman, Rosenberg, et al

LEGAL MANEUVERS: Insiders say Aaron Rosenberg, who is widely considered to be one of the hottest young entertainment attorneys in the business, received an overture from Allen Grubman to join the iconic dealmaker’s firm, amid speculation that Grubman intends to open a West Coast office. But even with Grubman’s reputation as the dominant music attorney of the last several decades, he was apparently unable to persuade Rosenberg (whose star-studded client roster includes Justin Bieber, Jennifer Lopez, John Legend, Brandon Creed and Joel Klaiman) to leave Myman Greenspan Fineman Fox Rosenberg & Light. On the same subject, if Grubman is indeed on the hunt for a new player, what affect will it have on his heir apparent, Kenny Meisalas? And will Grubman’s possible West Coast move create a domino effect, causing other entertainment-law firms to begin to think about following suit? More in I.B. Bad’s latest column. (6/21p)
