Slomo Rock (for slow motion) called Sigur Rós their musical style times. On Hvarf you can hear the first time sound like the Icelanders when they come off the slow motion. The direction has remained but the pace, both the music and the formerly very slow unfolding song structures, attracts. With new songs and new versions of old pieces alike. That may not taste any of the won meditative time expansion of previous albums like, but who would expect that a new Sigur Rós CD just sounds like the previous one? The constant development is downright trademark of the band. All those except the quartet were far too esoteric ethereal will welcome the turn to rock. Fans of Ágætis Byrjun, Takk & Co should not whine about the new development but look forward to this next step. Sigur Rós have reinvented pop music and reinvent themselves with every album also to be unfaithful again without so well with this. Full marks for that! The second CD home offers old songs of all previous albums, live and recorded semi-acoustic in new versions. To do anything you say. The sound is top notch, the music anyway. A must for fans and those who need it to become one.
