In their search for ever weirder, more punishing beats, underground US hip hop has been foraging way further into the dark recesses of the European avant garde than Kraftwerk in recent years. Which is why this apparently unlikely collaboration is actually so logical. From its opening, “Imagine What We Started”, with its filthily phosphorescent plume of industrial noise, Faust lay down for NY hip hop trio Dalek an assault course of rusted, twisted metal. Dalek rise to the challenge, using the backdrop as scenarios for their own paranoid, hellish monologues. Gruellingly awesome.
