Britney Spears’ latest album wasn’t much of a success critically or commercially. Our reviewer called Britney Jean nightmarishly blank, and Garth Brooks pummeled the thing in first-week sales. But none of that matters much since that will.i.am-afflicted set was a mere appetizer to Piece of Me, the Y2K-pop star’s massive Las Vegas residency that kicked off last month. Above you’ll find MuuMuse’s 15-minute trip through the show, which features hits new and old, copious costume changes, and at least one hairy man-arm bouncing ecstatically in the foreground. Whether or not you agree that Spears’ dancers, well, dance circles around her, the intensity of the spectacle cannot be denied.
