The base of The Dodos' sixth record is a driving acoustic rattle; without the drawled, circling vocals and squalls of fuzz, songs like "Retriever" could be called folk-rock. Cavernous drums and bright braids of guitar carry the brief "Bubble" to a spacey climax; an agitated rhythm section gradually energizes the glazed melodies of twin epics "Precipitation" and "Pattern/Shadow." For a compact statement of purpose, try "Goodbyes and Endings," which climbs a vine of stuttering, spiraling drums upward to pillowy harmonies.
