Sigur Ros are to take over YouTube tomorrow (March 7th) to screen their full-length documentary entitled 'Heima'. The documentary was filmed in Sigur Ros' homeland, Iceland, as they toured playing varied venues such as caves, fish factories and community halls. They will be the first ever band to have a full-length DVD screened on YouTube. They will also select ten other videos to broadcast as well as a message for their fans on their latest tour and album 'Reykjavik'.
