Veteran U.S. rock band Matchbox Twenty, with more than 30 million discs sold, will be one of the attractions at Rock in Rio 2013, the organizers announced Friday.

The band led by singer and pianist Rob Thomas, which has never performed in Brazil before, will be one of the big draws on the night of Sept. 20 at the Palco Mundo, the festival's main stage.

The American rockers are using Rock in Rio to promote their disc "North," launched in 2012 to become the group's first album to top the Billboard chart and which is the theme of their tour this year.

Rock in Rio 2013 is the event's 13th edition and the fifth in the Brazilian city where it all began in 1985.

This year's festival has concerts scheduled for Sept. 13-22 and a daily audience capacity of 85,000 fans in the so-called City of Rock, which will add up to a total of some 595,000 concert-goers.

Among the headliners already announced for this year are Metallica, Alice in Chains, Sepultura, Ghost, Beyonce, Iron Maiden and Slayer.

The previous edition of the festival in Rio de Janeiro, in 2011, attracted 700,000 people over seven days to see artists that included Coldplay, Mana, Snow Patrol, Red Hot Chili Peppers, Elton John, Stevie Wonder and Shakira. EFE
