Well I know probably as much as you do, they are from Iceland and they started up I think about 4yrs ago now....

My roomate knows one of the band members, but I don't know any of them personally...

They sing in Icelandic, but mostly what he sings is actually not any language at all, he calls it hopelandish... Its very unique, and it sounds so very cool..

Sigur Ros is doing very well in Europe, but they haven't really gotten enough attention yet in North America. They did manage to get onto the soundtrack for Vanilla Sky, basicly the director or producer heard sigur ros and insisted he get them on the soundtrack.

Sigur Ros also performed on Kilborn a while back, so obviously they are slowly gaining attention in North America. The critics all highly praise sigur ros, I am betting in 5 years time they will be a world famous band.... That is if people have any taste

I'd recommend checking out www.sigur-ros.com, they have some video stuff there to check out.... I have also the Kilborn video, and a bunch of other stuff, if anyone wants any videos let me know and I'll try to set them up on my FTP....
