The numerology behind 3121's album title might refer to it being Prince's 31st studio album (which was released on the 21st of March) or, as he told a BET audience, to Psalms 31:21. Regardless of any arcane provenance, the album's "Black Sweat" was a clear highlight. The song's use of sonic negative space and its deep sensuality called to mind Prince's classic single "Kiss." Over his nastiest groove of the decade, he deploys a high, squealing frequency usually reserved for G-funk and Neptunes productions and promises to have his lover "screamin' like a white lady." On the strength of that single, 3121 debuted atop the Billboard Top 200 album chart. Astonishingly, it was the first of Prince's albums to do so.
