In case anyone missed it, and be sorry if you did, I have uploaded the Sigur Rós portion of BBC's recent feature on them which aired on The Culture Show. It's about a 1/2 hour, featuring interviews and live performances from Heima as well as the BBC Proms show they filmed just before the London screening of Heima.
