The following message has been posted on the Season Of Mist Website:

We're sorry to announce that Arcturus' bassist Hugh Mingay recently had a motorcycle accident. He's going to be well, but has to rest for several weeks because a vertebra has been affected. Consequently, the three Norwegian shows scheduled this week had to be cancelled. We all wish Hugh to recover soon.
