They have announced the timetable on the Facebookpage, Björk is able to play 1h35m if she wants to. I am intrigued by the Björk Conference in the afternoon, though!
I wouldn't have cared! (Dutch people can stand a fair bit of rain)
Also it is hard for the festival, she was their main headliner.
Ofcourse it is always tricky to go to a festival for one artist, but they really relied on her. They even had a special lecture in the afternoon on Icelandic music!
Shame I won't be seeing the festival, I have only heard nice things about it. But the rest of the Saturday is not enough for us to go now.
