This was an added concert and is currently the final Björk date scheduled in Reykjavík. It is also in the large Eldborg room, rather than the Silfurberg hall where all the other Biophilia concerts have been held.
The show originally sold out in minutes, but they have just opened the two sections directly above the stage on the left and right side.. basically front row. I believe there are only 20 seats in each of these sections, so hurry and get them if you are still hoping to see this show!
