You can’t accuse Nina Hagen, regarded as the godmother of German punk – and the soundtrack to former German chancellor Angela Merkel’s departure from power – of being predictable or repetitive. Shadrack, the opening to her latest album Unity, is a Bible story half-sung over a synth-funk meets hip-hop beat, and sets the tone for an album that is wildly eclectic to the point of chaos. Moving from dub to funk and rock to folk, with covers of Bob Dylan and Sheryl Crow, Unity sounds as if records have been randomly pulled from a vast collection and assembled as one.
