Cut Copy's new album, In Ghost Colours, is discotheque perfection—dizzy, delirious dance rock, alternately euphoric and melancholy, with more than a hint of New Order at their ecstatic electronic peak. Lead singer Dan Whitford's soft crooning floats on thick, pulsing bass that occasionally wanders up the frets, live and programmed drumming, washed-out guitars, and glittering synth arpeggios. Live, they are mission control, orchestrating audience liftoff with nary a problem. With last year's great blog hope Black Kids and the dependably bittersweet Mobius Band.
