Here's a phrase you don't read very often: One of the biggest bands to ever come out of Iceland. Sigur Ros have gone through numerous personnel and style change since it's formation in the 90s, but their music has always been unique. This album, their fourth, is difficult to categorize. It is atmospheric and ethereal, with guitars played with bows (instead of picks), drums that aren't designed to keep rhythm, lush orchestration, and an abundance of chiming sounds. The songs on this album have found their way onto soundtracks, sports television themes, and commercials more than they have the radio. But there are songs here, just maybe not in the conventional sense of the word.
