After the mega-success of "Purple Rain", Prince was visited by the demon of Temptation. As he said in an interview, "Do you know how easy it would have been for me to just do another version of Let's Go Crazy?" But Prince smote the demon and posted a Dilettantes Not Welcome sign outside the purple clubhouse with this willfully peculiar record. That took more guts than I'll ever have, and the Skinny M.F. gets eternal props from me for it.Unfortunately, the music doesn't hold up. Except for the perfect single "Raspberry Beret", these songs just sort of slouch all over the place, never really coming together. But great days were coming...
