Dilla's best work is exhilarating and disorienting. Drums stutter and jerk; sirens wail nonstop; and snippets of wiry noise snake in and out of the mix. It is aggro psychedelic hip-hop that grabs you, sinks its hooks into you and won't let go. This album, overseen by his mother and mixed by Pete Rock, is probably Dilla's best posthumous release to date, touching on everything from the alien orgy funk of his mid-period work to the haunting soul of later years. Raekwon and Black Thought drop by, but the star is Dilla's gleefully idiosyncratic production work.
