Production Simple released a statement on their Facebook page.
Death Cab for Cutie must regretfully cancel tonight’s show at Iroquois Amphitheater, due to Ben being very sick. Though the band hopes to return soon, unfortunately, there is no rescheduled date at this time. All tickets will be refunded at the point of purchase. We appreciate your understanding and hope to make up for the inconvenience as soon as possible.
As noted above, refunds are available at point of purchase. There is currently no rescheduled date for the event.
