Rock in Rio is the largest musical festival in the world and so, it’s only fitting that some of the biggest artists have already been announced as headliners for the show. As of now, only three bands have been announced, but they’re huge names, and you can expect many more names to be released soon.

The festival will run from September 19 – 22, 2013 with Metallica headlining the first night. That’s fitting, seeing as how it’s their sixth time appearing at the festival. Metallica wrote on their official website, “We are super psyched to be returning to Rio de Janeiro, Brazil. How’s that for advanced planning?!” That last bit was a remark towards their announcement last week that they’ll be playing at the Voodoo Festival in just over a week. The short notice was due to the fact that they’re filling in for Greenday as Billie Joe Armstrong spends time in rehab.

Aside from Metallica, who else can you expect in Rio? Bruce Springsteen and the E Street Band will headline on September 20; and Iron Maiden will take over on September 22. There’s still that September 21 date to be filled in; but that’s just one of the many announcements we can expect in the coming months.

Those in Brazil will be able to purchase their Rock in Rio tickets as soon as October 23; but anyone outside of the country will have to wait until April 2013. Hundreds of thousands do flock here every year though, just for this festival, so make sure to start saving up for your trip to Rio next year!
