Having wowed the audience at her sold out Sydney Opera House forecourt performance on Wednesday January 23rd, it has been revealed that Icelandic pop-princess Bjork is now no longer appearing at the Sydney Big Day Out on Friday January 25th.

Her shock cancellation comes due to medical reasons, with doctors advising her not to perform due to swelling of her vocal chords. On her first tour of Australia in 12 years, the visit has not come without controversy so far, with Bjork lashing out at a photographer in Auckland last week.

Big Day Out organisers have offered a full ticket refund to any purchaser no longer wishing to attend the Sydney festival, however a partial refund is not available. It is unclear at this stage if Bjork will be forced to also cancel remaining Big Day Out dates across the country.
