Even if Rio de Janeiro is the famed birthplace of bossa nova, this Saturday, there'll be a different sound rocking Copacabana Beach. Aging rock icons The Rolling Stones are putting on a free concert expected to bring in over one million fans from all around the world.

The band will stay at the Copacabana Palace Hotel, and security is so tight that a walkway has been constructed six stories above Atlantic Avenue from their hotel suites to the immense stage built just for the show. There will also be over 10,000 police officers placed all over the city.

Reuters reports that the concern for the band's safety has something to do with the fact that Brazil's capital is plagued by drug warfare in the slums, and violence frequently erupts not just in the poorer areas, but the downtown tourist regions as well. In a population of just over six million, there were more than 6,600 murders last year. The Copacabana district, once a thriving hotspot in the '50s, is now known more for its sex trade workers and drug dealers. While it might seem like the Stones would be right at home, the band will stay clear of that sort of debauchery.

Of the million attending, there will be 4,000 VIP guests including vocalist Mick Jagger's seven-year-old son and his mother and Brazilian supermodel Luciana Gimenez. The special guests will watch the show from an enclosure next to the stage. "It will be historic - in the sense that they are in their 60s and they can still pull in a million people. I don't know how they do it," Paul Lester, the deputy editor of "Uncut" magazine told Reuters. "The Stones are really a multinational corporation. They're up there with McDonalds and Coca-Cola as a recognized world brand," he added.
