Из-за серьезных проблем со связками артистка вынуждена отменить ряд концертов, в том числе и свое выступление на Пикнике Афиши.

With a heavy heart we must inform that the further shows of Biophilia tour, including Moscow Afisha Picnic July 21st, must be cancelled.
Even though Bjork wanted to perform the shows, doctor’ advise was not to continue with the shows as they could bring a permanent damage to her voice, and to start rest and treatment immediately.
We are very sorry about any inconvenience this might bring, and appreciate your understanding.
