Aboard a private Gulfstream jet to Ronson's Pull My Hair Out video shoot in Los Angeles, Dash brushes aside the skeptics. "With Jay done, we have to take some chances, try new things," he says. His entourage surrounds him. The head of his film business peruses a script (she recommends that Dash take a pass). A marketing guy is reading Mao in the Boardroom, while two others flip through a branding book. Dash punches at his BlackBerry. "This is the smallest jet we'll ever be on," he says. True if Roc-A-Fella sails through the rough weather that inevitably lies ahead for any young and growing business.
