Prince to do 21 concerts in London, then study the Bible.
At some point I'll write my definitive Prince music review... Most fans probably look to 1999 and Purple Rain as his best work. However, his best, most musically creative period was 1992-1995, beginning when he shed his name to become "the artist formally known as..." and extending to Gold Experience. Emancipation had its moments, but essentially marked the swan song of a blessed period.
All that said, I haven't heard 3121... although Rave Un2 the Joy Fantastic sucked and sucked hard.
