Sigur Ros. My favorite album is called ( ), and they released it with all the tracks untitled. The whole album is sung in a made-up language called Vonlenska. Later on they went back and gave the tracks names and translated the invented language. It's really pretty, and they are very hip, in part because they aren't that well-known. Plus Pico Iyer is a fan! How can you go wrong?
This is the first track on the album. It is a beautiful haunting sad song (I listen to it a lot at work for this reason).
The video is unsettling and creepy. In a good way.
