Whatever happened to Chicago’s Nathaniel Pierre Jones, the man who in 1986 tweaked a Roland 303 with his crew Phuture until he created “Acid Trax” and put dance music on the tongues of millions worldwide? Brother’s still workin’ it, as seen on this opaque follow-up to his springtime epic single, “Overcome.” “Break It Down” offers some of his trademark warped “Wild Pitch” style over a filtered structure, with fractured jive vocals by an unidentified female. The party’s never ended. Go on, Pierre.
