Just when this Icelandic crew seemed stuck in loud/soft/loud/ soft rut a la Mogwai or Godspeed You Black Emperor, they release their most beguiling, subtle and beautiful album yet. This album, allegedly the group's first sung in Icelandic rather than their own made-up "Hopelandic" (not that this listener could tell the difference) is relentlessly joyous, unaffectedly rad and inventive but never just for its own sake. Strings hold an ever more prominent place in the music, and this is a good thing. Songs unfold slowly as usual, but they take unexpected turns as often as not. The brilliant "Glósóli" burbles with as much melodic invention and anything by their fellow Icelanders Mum. Takk is a delight from start to finish, managing to be both their most accessible and experimental album yet.
