With their arrival onto the ever-blogging indie music landscape, New York City’s Afropop-cribbing Vampire Weekend became poster boys for the late Aughts’ surge in world music-influenced indie rock. And while I’m all for the sort of East-meets-West, Graceland-esque mentality that brings creeds and races together like a United Colors of Benetton ad, there’s something just a touch disingenuous about a group of Columbia University grads who refer to their sound as “Upper West Side Soweto.” Yes? No? Regardless, no need to feel quite as trepidatious in regard to the legitimacy of Los Angelenos Fool’s Gold. Core members and principal songwriters Luke Top and Lewis Pesacov were both born in Israel, a handful of their tunes are sung in Hebrew, and the lineup has featured members from all over Central and South America. But even more than their sundry roots and music-school chops, the element of Fool’s Gold that shines the brightest — especially on their sophomore LP, last year’s Leave No Trace — is their knack for fishing lustrous, spellbinding melodies from myriad diverse sounds. Tracks like “Wild Window” and “Balmy” are as exotic as their titles suggest, with rhythms and grooves that are at once tropical, mysterious and familiarly danceable.
