Sigur Rós are an Icelandic band whose music, though unique in style, harks back to the days of 70's progressive rock. They are often given the relatively obscure tag of "post-rock". I was first introduced to the band through "Takk", and it is still my firm favourite of all their albums. The album feels epic in proportions right from the introduction, and carries an ambiance that no other band has ever achieved. The band have a strong sense of melody, and their instrumentation is close to perfect. The result is ethereal, and the album has an ability to transport you from wherever you are to a completely different world. There are moments on this album which will stay with me forever, like the repeating strings at the end of Andvari, the climactic heights of Mílanó and the beautiful introductory chords of Heysátan (granted, that's an unfortunate name in English). Once you can get over the sheer weirdness of the vocal style, and eventually come to love it, you'll probably understand why I'm making such a fuss.
