Seems strange to bring Stuart in if Kevin is still in post as her musical director but if he's doing what Mike Dean did with the Rebel Heart tour and sprinkling his magic on some tracks then that would be fantastic!
Hope this means they actually work on some material too for her new album, especially if it's the pure pop spectacle hinted at by her working with Max Martin.
It'd be something if she brought back a bunch of her old producers to make a new album or EP or something to celebrate her back catalogue. It would kind of fit the theme she's going for. Wasn't she just rollerskating with Nile Rodgers?
