If you've got tickets to the Eros Ramazzotti concert scheduled for this evening, don't start heading up Montjuïc just yet—the concert has been pushed back to the same time (9pm) tomorrow, February Tuesday 16th. The reason being that during the set-up of the stage for the Italian singer's show, some technical problems were discovered that caused the organisers to postpone the concert for 24 hours.
All tickets bought for tonight's concert will be valid for tomorrow. If you are unable to attend the concert tomorrow, you will be able to get a full refund from the place that you originally bought your ticket(s)—this refund is available for the next 15 days.
And if you hadn't got your ticket yet, and thought it was too late, fear not—there are still a few available from Telentrada, Serviticket and Ticketmaster.
