Rock in Rio is a series of music festivals held in three cities: Rio de Janeiro in Brazil, Lisbon in Portugal and Madrid in Spain. Four incarnations of the festival were in Rio de Janeiro, in 1985, 1991, 2001 and 2011, four in Lisbon, in 2004, 2006, 2008 and 2010, and two in Madrid in 2008 and 2010. The shows were organized by Brazilian entrepreneur Roberto Medina. In 2011, Rock in Rio is taking place in its original home, Rio de Janeiro.
Rock in Rio has been the largest music festival in the world, with 1.5 million people in the first edition, 700,000 in the second, about 1.2 million in the third, and about 350,000 people in each of the 3 Lisbon editions.
The first edition of the festival was held from January 11–20, 1985. Queen, George Benson, Rod Stewart, AC/DC and Yes were the headliners, each occupying top spot for two nights (Benson, however, ceded it to James Taylor for their second night in the same bill, due to the huge delay Taylor’s extended performance had caused to his concert two days before). About 1.4 million people attended the 10-day-long festival.
