I hate to say this but I'm disappointed. Sigur Ros are the type of band who deserve to get all the superlatives thrown at them as they want. They are probably one of the greatest bands in the world and certainly one of my favourites.
Unfortunately this film just doesn't portray them as they deserve to be. Its presentation sounded appealing (lots of black and white grainy footage from many different angles) but prevents you from getting involved in the performance. It's hugely self-indulgent; I can see what the film makers are trying to do but Sigur Ros' music should be the star of this film.
Interestingly, if you watch the bonus videos they've not been fannied about with as much (yes, that is a technical term) and it's much nicer to watch. However, they've not mastered these into DTS Master Audio which is a shame.
The double CD is a great bonus and this is a great value package but the film (which in fairness is what you're buying) is a little bit of a let down. Sometimes I felt the drums weren't recorded/mastered well enough as they lack a bit of punch.
My advice would be to just watch 'Heima' which includes lots of intimate 'session' performances, great interviews and the odd live performance. It's the sort of film that makes you want to move to Iceland and take up the flugel horn.
I was perhaps looking forward to this a bit too much so there's always the expectation factor but the visuals turned me off. Still gets a good rating as the music is great and you get a lot for your money.
