I'm kinda hoping they stay with this somewhat happy sounding stuff they've been doing lately. I saw Sigur Ros last fall, and the songs from Med Sum thingamajig were OUTSTANDING live. I never expected to be dancing around at a Sigur Ros show.
(that said, they also played a ton of stuff off Agaetis Byrjun, yay)
(also, Jonsi's boyfriend's band Parachutes opened, and they were epic fun. I put their first EP in the Mediafire thread a few months ago, if you guys are interested)
