DJ iconoclast Curtis Jackson schools house fans again on a double-disc mix that pits his most famous alter egos against one other. Taking a typically rapturous turn on the soulful Cajmere disc, he really rocks the vocal tracks, integrating them with the same precision a jazz drummer applies to slipping in drum fills. Alternating between tribal chants, singer Dajae’s gospel-strength roar, and the gibberish sounds of a ranting old man, Jackson showcases the human voice as a varied and powerful instrument. The acid-drenched Green Velvet disc is a lesson in keeping after-hours parties dirty and unhinged. A schizophrenic masterpiece.
