These are 2 of my favorite videos of all time. More than any other band, Sigur Ros always seems to capture something in their music videos. As I don't understand a word of the actual lyrics, my experience with their music is purely based on sounds and the feelings they emote in me. Somehow, these videos seem to perfectly embody what the music makes me feel. These 2 videos are perhaps the best examples.
Buy this band. Love them.
