Thankyou very much to a person called murderscenerevenge who went to the sigur ros gig armed with a mobile phone. Here are some of the (many) highlights of the gig.
Flotjavik (look at the pretty lights)
Hoppipolli / Meo Blodnasir (Great version, stripped of strings and brass, it rumbles like a train.)
inni mer singur vittleysingur (look how they almost lost it on the bridge-y bit)
gobbeldygook (audience handclaps, support band on drums, SPANGLYBOOM!!!)
Apparently, murderscenerevenge has more to put up, so i'll post those too, like the geek i am.
