Sol Invictus concert cancelled

Sol Invictus will not play at the Dark Nations festival in Vienna.
This is the statement of the organization:

“Dear friends of Dark Folk, for about three weeks our venue and the producer have received anonym mails, which contain threats against the gig of Sol Invictus and the venue. To protect the band we decided to cancel the gig. We are trying to supersede Sol Invictus. More soon. Sorry, but violence against bands is not what we need or want here in Vienna. Your DND-Team”
