There have been massive changes on the A&R front over the last few months. Among the most notable changes include the return of Rob Cavallo as Chief Creative Officer for Warner Music in California, Ed Johnson joining Warner Bros. from EMI Music Publishing, and Darby Bowen joining Epic.  Over in the UK, there was a lot of activity as Zack Strubel joined Columbia, Jos Watkin joins Parlophone, Scott Jason joins Polydor, and Steve Proud joined Warner Bros. Ollie Hodge returns to Columbia-UK from his short stay at Columbia–NY, Angus Blair exits Island, Marc Jones exits Columbia, and Gary Harris exits Warner Bros. In New York, Steve Ralbovsky’s label Canvasback Music joins Atlantic from Sony while Pete Giberga exits Epic, Daniel Davis exits Atlantic while Jamaal Meeks exits SRC. And the big label news (as in not so quietly kept secret) is that Universal Music Group’s CEO Doug Morris is making plans to have Universal’s international chief Lucien Grainge take over as CEO sometime this summer (Morris is expected to remain as Chairman).
