“Loud speakers sound, white disco light,” goes the climactic chorus of “Pharaohs And Pyramids,” but Dan Whitford’s imprecise imagery isn’t needed: Cut Copy’s music successfully achieves synesthesia on its own throughout the Aussie quartet’s third full-length. With singer Whitford on the boards (taking over for DFA producer Tim Goldsworthy), each arpeggiator pattern, glow-worm guitar line, and percussive thump on Zonoscope bobs in the mix as a luxuriously distinct spot of sound. And rather than solely packing the lushness into radio-ready structures as it did on 2008’s In Ghost Colours, Cut Copy often lets the arrangements ride, most spectacularly on the six-minute round-and-round rave of the opener, “Need You Now.”
