Even as a married Jehovah’s Witness approaching the age of 50, Prince still sounds horny. His twenty-fifth album sharpens the focus of Musicology, 2004’s sultry return to form, stripping his classic sex funk down to its elements: anvil-heavy beats, grungy guitar and soft-to-shrieking bedroom vocals. The results, following the pattern of his recent records, aren’t perfectly even. On “Te Amo Corazon,” a soggy Latin ballad, and “Get on the Boat,” an up-with-people jam in the spirit of Parliament-Funkadelic, his everpresent ambitions swamp his primal drives. But the minimalist tracks rate among his best. “Black Sweat” unveils the bump-and-glide blueprint Pharrell Williams has been working from, and the raw, noisy “3121” updates the apocalyptic party smash “1999” for a dark new millennium. More than 25 years after he sang about screwing his sister, Prince is perfectly sauve fighting off father time.
