A faintly preposterous man, much of Topher “Gold Chains” LaFata’s music concerns the international pursuit of well-dressed booty. In a way, he’s a classic hip hop reinvention: a computer geek rebranded as globe-straddling love-magnet who raps, a touch emphysemically, like Tone Loc. Nothing on Young Miss America quite matches GC’s superb first two EPs. Nevertheless, he and producer Kit Clayton still filter R&B, techno, Bollywood, electro and much else through their laptops, and the elaborate raps?more serious than they first appear?make for an inventive debut.
