The year 1985 saw the birth of two iconic names in modern music: the debut success of the legendary Norwegian band a-ha, and the launch of the world famous Rock In Rio music festival. In 1991, a-ha played the festival for the first time: their concert, in front of 198,000 fans at the Maracanã Stadium, was a world record for a paying audience. To celebrate both the festival and the band’s thirtieth anniversary year in 2015, the band have been invited back to perform at the festival for a second time. In September 2015, a-ha will return to Rock in Rio for what promises to be a very special concert.
