Whereas Takk … and Ágætis Byrjun were reminiscnet of august, icy floes and glaciers, and Von and Ba Ba Ti Ki Di Do conjured images of sleek sheets of black ice, Sigur Rós’s latest album goes to great lengths to prove that Iceland is also capable of producing flora and fauna. Xylophones and a brass section replace crash cymbals and drum-and-bass interludes common in earlier singles (“Sæglópur” and “N‡ batterí”). Jónsi Birgisson & Co. suddenly sound more like Panda Bear & Co. circa Sung Tongs and less like a calmer Explosions in the Sky, a less twee Múm or other oft-compared acts.
