On paper, the marriage of talented leftfield hip-hoppers Serengeti & Polyphonic seems like a match made in heaven. Geti’s stream-of-consciousness flow easily matches up with the best of the Anticon MCs, and, at its best, recalls the vocal acrobatics of true giants like DOOM. Polyphonic’s production is equally impressive—dude has more in common with Plaid and Boards of Canada than Timbaland. Yet all this talent doesn’t make Terradactyl a particularly compelling listen. Geti’s dense tongue-wagging is in serious need of a little bounce, yet Polyphonic’s skittery electronics (which are probably better suited for an instrumental release) only clash with his partner’s raps. With these kinds of irreconcilable differences, Serengeti & Polyphonic might need a divorce.
