Listening to this album, the slap is assured. Icelandic Sigur Ros and exceptional post rock take you into a world where everything is qu'atmosphère planing and relaxing. An exceptional song, a child vocalizes, do not try to understand the words, they are "Hopelandic" (language created by the singer). The instruments accompany the singing beautifully, sometimes distorted guitars, a ramp that takes you to the guts, to crown on the whole, the singer plays guitar with a cello bow, making an entrancing sound. Each title is exceptional, Agaetis Byrjun is well and truly the best album of Sigur Ros.
