Metallica may not be releasing new music until 2014, but that doesn't mean you won't still hear them next year. In fact, the band has just announced a headlining appearance at the 2013 Rock in Rio festival in Rio de Janeiro, Brazil. Joining Metallica as headliners are fellow metal mavens Iron Maiden and classic rockers Bruce Springsteen & the E Street Band.

This will be Metallica's sixth time playing the festival, and they're set to perform on Sept. 19. Pre-sale tickets will be available Oct. 23 for those who have Rock in Rio membership cards, which are exclusively for Brazilian residents. Further information can be found here. For those outside of Brazil, there will be an international ticket sale beginning in April 2013.

At present, the only other shows on Metallica's schedule beside Rock in Rio is their appearances at Australia's Soundwave Festival early next year and at New Orleans' Voodoo Music Festival on Oct. 27 of this year. The band recently stepped in to headline Voodoo when Green Day bowed out as frontman Billie Joe Armstrong continues rehab for substance abuse.

Iron Maiden, meanwhile, have a number of European festival dates scheduled for June and July of 2013. Their headlining slot on Rock in Rio will take place on the closing night, Sept. 22.
