Who can take a Grateful Dead raga, sprinkle it with a Steely Dan jam, cover it with a Snoop Dogg soundbite, and a miracle or two? DJ Jazzy Jeff can — yes, he of Fresh Prince fame. And he does just that — and much more — on two free hour-long MP3 files of live sets available on the website of Club Six, a loungey nightspot on one of San Francisco’s historically least desirable blocks (visit clubsix1.com and click on the “music” tab). Certainly on their own, each of the elements in Jazzy Jeff’s stream-of-consciousness DJing is hardly electronic-oriented — with the exception of the occasional snag of instrumental hip-hop, or the bit of Suzanne Vega a capella from “Tom’s Diner” whose unintended adoption once upon a time by a host of remixers served, in retrospect, as a prototype for DJ Danger Mouse’s copyright-eschewing Grey Album. But sewn together, into a running commentary on unlikely parallel riffs, they’re evidence of a man wholly able to play with the raw source material provided by pop culture, one who takes FM staples and turns them into something enchanting, humorous, continuously surprising — jumpcuts between decades and genres, subtle swaths of light scratching, and endless choice hooks. Jazzy Jeff mixes it with love, and makes the world taste good.
