Hot Chip, ‘In Our Heads’

One of Hot Chip’s earliest singles was “Over and Over,” and it was easy to imagine that the band would make good on the title, pumping out a string of electronic dance-pop songs that differed from one another only in the order and pitch of the bumps and bloops. Fifth album “In Our Heads” features its share of cerebral hip-shakers, but the group has enough other moves to keep things varied.
