Imagine the volume and range of noises Bjork'd make...
They'd take your ears *clean off*.

As they are headlining, I would hope for quite a long set. I have seen them perform five times now, and they have played my personal favourite 'Com (?)' at three of these shows, and '1612' or 'Lost Snow' at the others. They usually seem to have a set list with a few gentler songs, and then a few ear destroyingly loud epic numbers.
The first two times I saw them, they were playing mainly from 'One Step More and You Die' then at the next two gigs, they played mainly from'Walking Cloud and deep Red Sky...' The last and best for me, when they played at The Islington Acadamy, they played a long, loud and stunning set, that included all my favourite songs from across their three albums.
I do hope they play 'Com (?)' this time.
