METALLICA's first-ever concert in India, which was scheduled to take place tonight (Friday, October 28), in Gurgaon has been postponed until tomorrow evening as a result of technical issues. According to local media reports, a surge of people caused the barricades at the venue to collapse earlier this evening, with some fans gaining access to the stage area and damaging equipment in the process (see video below).Approximately 20,000 people turned up for the gig, many of whom travelled to Delhi from across the country and abroad to see the world's biggest metal band perform. According to RollingStoneIndia.com, "Things started heating up with a stampede at around 3:30 in the afternoon. The stampede caused the barricades to collapse, with several fans getting hurt in the process. As the crowd entering the venue continued to grow, the barricades in front of the stage also collapsed. At around 6 p.m., the organisers announced that due to 'serious technical difficulties,' the show was postponed and METALLICA would play at 4 p.m. tomorrow. "The announcement further fueled the crowds frustration, causing fans to go on a rampage. Several fans gained access to the stage area, setting fire to banners and causing damage to the LED screens, monitors and other equipment." HidustanTimes.com reports that the METALLICA concert in Gurgaon is likely to be canceled, said TV reports on Friday. The reports also suggest that the stage for the performance is being dismantled. Earlier, the organizers announced that the gig was postponed until Saturday because of security issues. While the organizers initially claimed that it was due to some technical glitch, the band reportedly decided not to play after fans broke through barricades at the venue. Vishal Dadlani, vocalist of Mumbai-based electronic band PENTAGRAM, said that the postponement was caused by "Delhi's enthusiasm" and that "there wasn't any technical glitch" as was claimed initially by the organizers. "If the fans ransack barricades, then obviously the band can't play," he added. Eyewitnesses suggest that post announcement angry fans were seen trying to damage equipment near the stage and some even tried to set fire to banners near the stage. "METALLICA has let us down", said Rahul, a die-hard fan from Lucknow.
