It would be mind-blowing if it was actually newly produced music, as opposed to simply being previously unreleased music.
Allegedly there are thousands of completed recordings.
But they aren’t necessarily radio friendly (regardless of lyrics). Too long, too different from what else is in the marketplace, too different from his ‘hits’.
Any label is going to want to find a single to promote.
It’s being re-mixed with modern equipment and technology that was not available pre-1996.................
Given the quantity of unreleased stuff he has, it could be mind blowing. He completed albums, all the way to test pressings, and then just locked them in his vault. Depending on which confidante you listen to every actually released Prince album is matched by 1 to 3 unreleased fully cooked albums in the vault. Then there’s the movies. We could be getting “new” Prince stuff into the 22nd century before they have to dig into the rehearsals and other junk that’s typically released as posthumously new.
Whatever it is, I doubt it will top his 1986 album, Sign Of The Times. For my money, that was the last breakthrough record of his career.
