In a musical encyclopedia, “Impossible Broadcasting” would be the ideal entry under the heading “world fusion.” The membership of this U.K.-based collective is in constant flux, but that, if anything, keeps the vibe consistently compelling. Some of the enduring elements of TGU’s sound – reggae, trip-hop, Arabic music, sampling – are here, while sitar prodigy Sheema Mukherjee and Malian rappers Tatapound add further breadth to the groove. A fine place to begin is “Drinking in Gomorrah,” a surrealistic travelogue underpinned by a terrific dance beat. Move on to Tatapound’s rap on African corruption (“Cikan-le Message”) and “Yellow and Black Taxi Cab,” both tunes built on wicked beats.
