Last year, Pit Er Pat released the freewheeling Shakey, an album full of innocent eyes, wary synths, and preschool drums. Much has changed since: trading cheer for spook, and youthful exuberance for paranoia, the band’s divinely complete Pyramids is the sound of a matured band. Physically enthralling, the record’s 11 songs dig into the skin, trading anxious passages for nervous swells and terse verses for tense choruses. Shakey was what it felt like to chomp cotton candy and hold hands at the carnival; Pyramids is how a murder ballad sounds from the merry-go-round.
