Rating 4 Juaneco y su Combo: Masters of Chica, Vol. 1 (Barbes Records). A popular Amazonian garage band in the '60s, Juaneco y su Combo's twanging wah-wah guitar rhythms and percussions, mixed with electric style cumbia and rock 'n' roll is giving Andean-influenced "chicha" groove (featured in Brooklyn bars) a new-found popularity away from the Peruvian jungle.
