Two discs worth of exploratory, exhilarating deep-id indulgences that allowed Prince to play out countless pop fantasies, from the cotton-candy psychedelica of "Starfish and Coffee" to the slithering funk of "U Got the Look" to the tense minimalism of the title track. And if you want true guitar heroics, check the solo on "I Could Never Take the Place of Your Man", perhaps Prince's most potent rocker.
