According to Terra, a surging crowd of IRON MAIDEN fans caused a barricade to collapse during the band's concert earlier tonight (Sunday, March 27) at HSBC Arena in Rio de Janeiro, Brazil, forcing the group to cancel the show. The incident happened during the first song of the band's set (see video below), "Satellite 15 ... The Final Frontier", when the barrier separating the fans from the stage broke and the crowd rushed forward towards the members of the group. IRON MAIDEN's lead singer, Bruce Dickinson, noticed the commotion and urged the crowd to take it easy. He said, "Hey guys, please calm down. Everyone, take a step backward. The fence broke and it's dangerous. We do not want anyone to get hurt." The members of the band then stopped playing and Dickinson explained that they would resume in the concert in ten minutes after the fence had been repaired. The audience waited, but after 20 minutes, boos became more audible as the crowd began losing its patience. Dickinson then returned to the stage to break the bad news. "The fence is completely broken. We do not want anyone to get hurt," he said.Dickinson told the crowd that IRON MAIDEN will play at HSBC Arena at the same time on Monday (March 28), and that the fans should pick up a bracelet before leaving the venue giving them access to tomorrow night's show. "We cannot play tonight, but tomorrow, at the same time, we'll be here," he said. "Everyone who has a ticket or bracelet will be able to enter. Those of you who cannot make tomorrow's concert will be given a refund." The audience responded with boos and outrage before the singer made one last attempt to calm things down. "We were told that there is no way to way to get the fence repaired tonight," he said. "I know it sucks. But please do not break anything when you leave. Those of you who cannot make tomorrow's concert, we will post on our official web site information on how you can get a refund. I'm really upset. But I can assure you that tomorrow night we will have the best fence in the world." Dickinson left the stage and more boos followed. People threw cups on the stage and some kicked the fence as it lay broken on the venue floor.
