When Lyor Cohen left Island Def Jam back in January 2004 to join Edgar Bronfman Jr. as Chairman and Chief Executive of the U.S. unit at WMG, Julie Greenwald was supposed to stay put, according to all involved. Everyone jumped on board the “Julie is staying” bandwagon after she swore she wasn’t going anywhere. Once the dust settled, though, she quickly jumped ship to Lyor’s navy to help him rebuild Atlantic in conjunction with Jason Flom and Craig Kallman. And the rest of the story is history. If Lyor can raise enough money, most observers say she moves with him again…unless the Czar Blavatnik makes her a gigantic big-bucks offer to stay. We shall see.
