Hot Chip have always been the sort of band happy to flaunt their intelligence, but the smartest trick they pull on Made in the Dark is to show a little wisdom, too. 2006's The Warning was a fine record, albeit one sometimes difficult to ake seriously thanks to its taste for pop pastiche--here's the Prince track, there's a 2-step garage track--or the ccasional ironic wisecrack. On their third album, though, it's satisfying to report Hot Chip sound like no one but themselves. hat is, shuffling, synthesizer-smeared electro-pop with a gooey emotional core and, in the shape of Alexis Taylor, one of the greatest white-boy soul voices since that of his hero, Green Gartside of Scritti Politti.
