British electronic musician Mathew Herbert is known for his work with the likes of Micachu and Björk; for his soundtrack to the crowd-sourced Life In A Day film, which was nominated for an Ivor Novello; and for making house music. Here, though, we find him in conceptual electronica mode, which has previously meant driving a tank over a replica of the meal Nigella Lawson cooked for Bush and Blair, or recreating the 20-week life of a pig using instruments made from parts of that very animal. The End Of Silence is devised entirely from a 10-second recording of a bomb dropped in Libya. Herbert has compared the line-up to a jazz quartet, and he is joined in playing the manipulated samples by musicians including Tom Skinner, also seen with Mulatu Astatke, Sons of Kemet and his own Hello Skinny. This allows for an element of interplay and off-grid spontaneity, although TheEnd Of Silence is not – surprise, surprise – a jazz quartet album in any traditional sense. The music veers, rather, between industrial, musique concrète and neo-ambient, although our awareness of the source material makes even the mellower stretches profoundly uneasy listening.
