This third installment of the Tijuana Sessions series finds the core beat alchemists of the group -- Fussible, Bostich, Hiperboreal, Clorofila, and Panoptica -- extending their sequenced, laptop-driven sound with extra, organic sonics. Live tuba, trumpet, clarinet, upright bass, and vocals all lend a loose, jazzy, roc 'n' rol feel to these simmering breakbeat floor-fillers and downtempo head-nodders. Unlike a lot of multiculti, sample-happy "worldtronica," Nortec makes truly gritty compositions with a sense of humor and sophistication that stems as much from Tijuana's poverty as from its position as a millennial trading post between two exploding economies. "Esa Banda en Dub," the collective's collaboration with Arizona Tex-Mex jazzers Calexico, rambles down a dim, dusty, valley road with a glowstick in one hand and a blunt in the other. Other tracks feature a heavier house thump ("Revu Rockers," "Narcotéque") or funky, hip-hop snap ("Don Loope," "Almada"). The feeling of cultural collision is palpable but also natural and irresistible.
