A mainstay of San Francisco’s hip-hop scene, Peanut Butter Wolf (producer of Kool Keith’s “Wanna Be a Star” and Ozomatli’s “Super Bowl Sundae,” among others) has just released two different compilations: Fusion Beats, on Japan’s Brown Sugar/Cold Fusion, is a mix CD that ranges from old-school funk to underground hip-hop to classic reggae. The brand-new Peanut Butter Wolf’s Jukebox 45s, on his own Stones Throw imprint, compiles 22 of the label’s collectible seven-inch singles; artists range from the Highlighters and Breakestra, who re-create the instrumental funk of the late 60s and early 70s, to scratchadelic DJ A-Trak (“Enter Ralph Wiggum”) to rapper Quasimoto–aka Madlib, the middle act on this bill. As Quasimoto he put out one of 2000’s finest hip-hop albums, The Unseen, which sounded like a cross between Prince circa Sign ‘o’ the Times and De La Soul circa De La Soul Is Dead. As Madlib he’s also recorded with the straighter rap trio Lootpack, whose 1999 triple LP, Soundpieces: Da Antidote, is one of undie-hop’s signal releases, and with the weirdo jazz-funk project Yesterdays New Quintet, whose 2001 Angles Without Edges was an unfocused but promising album held together by an apparent obsession with the Fender Rhodes electric piano. His track list for this all-DJ bill will likely meander at least as much as his career. Egon spins first. Thursday, September 12, 9 PM, Empty Bottle, 1035 N. Western; 773-276-3600.
