After ten years, the world' s largest music festival, Rock in Rio, returned to its hometown Rio de Janeiro for seven days of concerts from Friday, September 23rd, attracting 700,000 people over the whole week．
It is the 10th edition of the Rock in Rio festival, but only the 4th to be held in Rio as the organizers exported the festival to Lisbon and Madrid ten years ago．The first edition of the festival was in 1985 and the most recent edition in Rio was held in January, 2001．A total of 700,000 tickets were sold out for this year' s festival．
The festival consists of four stages with the participation of International stars including Elton John, Katy Perry, and bands Metallica, Evanescence and System of a Down．Several stars which performed in previous editions are also on the list this year．．In addition, a number of local singers and bands will also join this year．
The performance site, named as Rock City, is a 150,000-square-meter area．Besides the concert area, the site also has a giant Ferns wheel, a roller coaster, and a small shopping mall．After the festival, the Rock City area will be converted into a leisure area to athletes in the 2016 Olympic and Paralympic Games in Rio de Janeiro
According to Rio' s tourism company Riotur, out of the 700,000 people expected in the festival, some 315,000 will be tourists, who raised the hotels' occupation rate to 98 percent．Riotur estimated that the Rock in Rio festival will bring 419 million U．S．dollars for the city and create 10,000 jobs．
The creator of the festival, Brazilian businessmen Roberto Medina, insisted on opening the Rock City gates himself, in the early afternoon, and greeted the first fans to enter the site．"We come to the gate because the Brazilian audience is even more important than the bands．We applaud them．They make the greatest show," he said．
