The theory that Hot Chip are ironists, blending diverse musical strands with a kinked eyebrow, has long been buried. Even so, their fifth album opens with a joyous rebuttal of such cynicism – a surging, synth-driven hymn to the possibilities of pop music. If nothing else here quite touches the heights of Motion Sickness, it's partly because, in keeping with that credo, they refuse to repeat themselves. Flutes is a terrifically chilly robotic workout, These Chains blends doe-eyed R&B and disco to fine effect. Night And Day's so-so electrofunk is the only casualty to this record's sense of adventure.
