In his 2003 book Possessed: The Rise And Fall Of Prince , author Alex Hahn spends a lot of ink on Prince's supposed need for control of every aspect of his life. It's Hahn's theory that this led directly to Prince's steady decline in popularity and creativity from the mid-'90s on. At the end of the book, Hahn openly wonders if Prince will ever be able to recapture the magic of his best music. And who could blame Hahn for wondering it? At the time, Prince seemed already a long way down the road that fallen stars like Elvis Presley and Michael Jackson had already traveled. Then came 2004. The year started with The Artist's induction into the Rock 'N' Roll Hall Of Fame, which was followed by a surprising return to recording form, Musicology , and a subsequent tour that seemed to be a triumph in every city. Even so, it didn't necessarily mean Hahn was wrong. After all, even Elvis had his '68 comeback special. The true test is the follow-up album.
