In this age of musical micro-genres, “Radio Nomadica” has no easy one-word descriptor. Electronica? That’s a big musical umbrella, instead try this description: “Classic down-tempo, trip-hop tunes interlaced with some world groove that features Desi, Asian and Middle Eastern-influenced styles and artists.” Tabla, sitar, flute and sinuous vocals thread through danceable beats. Petrol Bomb Samosa, anyone? No matter what you call it, it’s a fitting, flowing soundtrack for a Saturday night.
