With a new crop of Prince enthusiasts like The-Dream and newcomer Gordon Voidwell making names for themselves, it's no surprise that people like Foreign Exchange are gathering to pay tribute the artist formerly known as the artist formerly known as Prince. "Purple Flip" is the teamwork of the Foreign Exchange, ?uestlove, Zo! and Carlitta Durand. Even with vocals from Phonte and Durand, the track is dripping of "Purple Rain." But if ?uestlove is on drums, does this make him Sheila E? Or worse yet, who's Apollonia?
