On the duo’s fifth album, Thievery Corporation would have you believe they’re not just dub-influenced lounge lizards, but revolutionary propagandists. Taking cues from Fela’s slogan “music is the weapon,” they offer up a sonic jihad for the dancefloor. Radio Retaliation is their most thematically conceptual and far-reaching album yet, one that draws inspiration equally from Jamaican soundsystems, Mexican Zapatistas, Peruvian Communism, Hindu sacred music, Slovakian folk, DC go-go, and Brazilian favelas. Guests include Sleepy Wonder, Femi Kuti, Chuck Brown, and Seu Jorge, who lend the album a truly outernational feel. The end result is a tour de force of dreamy downtempo with sociopolitical substance, not just empty-headed fluff.
