Illinois native David Cohn, a.k.a. multifaceted rapper Serengeti, experienced two distinctly different childhoods growing up. Half of his time was spent in Chicago’s then all-black South Side with his mother — a secretary, atheist, and devout communist. The other half was clocked in the then all-white suburbs of Olympic Fields with his father — a stressed, middle-class business-owner. Though Serengeti is the great nephew of Sonny Cohn, Count Basie’s trumpeter of thirty years, music wasn’t passed down freely in the family. Instead, young David kept his musical obsessions in his head, and by the time he was ready to loose them, his skull had accumulated several album’s worth of left- field hip-hop detritus. Geti has since released fourteen albums in ten years. He made his first two nearly by accident, on the way to completing his so-called “debut,” Gasoline Rainbows. That triptych created a hefty rumble in the underground, showcasing stylish, heady raps intertwined with thick threads of soul, pop, rock and psychedelia. With 2006’s Dennehy — a character-based concept album loaded with Chi-town signposts and sports references — Geti established himself as the missing link between Kool Keith, Common Sense and Bill Swerski’s Superfans. Since, he’s been following a stream of consciousness through the darker corners of society and his psyche over an increasingly adventurous musical trajectory. In 2008 alone, Geti debuted two new projects: Yoome, an intimate electronic collaboration with a New Zealand chanteuse, and Friday Night, an exercise in deconstructed party rap with emcee Hi-Fidel. In 2009, Adam “doseone” Drucker (Subtle, themselves, 13& God) signed Geti and his sometimes production partner Polyphonic to Anticon. The pair released their sophomore collaboration on the label that same year, Terradactyl, which found the emcee’s bleak verbiage delivered in both rhyme and free-floating sing-song over an intricate and glitchy expanse of experimental electronics. Fifteen months later came Serengeti & Polyphonic’s double EP, Bells & A Floating World, which featured six brand new songs and as many remixes, including inspired reworkings by artists as diverse as WHY?, Bracken, Jel, Son Lux, Greetings From Tuskan and Epstein Y El Conjunto. 2011 is looking to be one of Geti’s busiest years yet, thanks to Anticon’s release of Tha Grimm Teachaz’ long-lost cassette-only classic There’s a Situation on the Homefront (Geti helped bring the formerly shelved 1993 album to the label) and his contribution to Asthmatic Kitty’s ongoing 7-inch series. His latest Anticon release is Family & Friends, a refreshingly upbeat full-length produced by WHY?’s Yoni Wolf and Advance Base, formerly known as Casiotone For The Painfully Alone.
