There's no doubt that the Rock in Rio festival is one of the world's premiere events, so you would need an equally entertaining city to pull off such a festival in the U.S. As such, organizers will expand the Rock in Rio brand to include a pair of U.S. music weekends in Las Vegas next May and they've pulled in some big names to get the ball rolling.

Metallica will be one of the headliners on the Main Stage during the rock weekend, with Linkin Park and Deftones among the initial rock acts expected to take the stage during the weekend of May 8 and 9. The remainder of the bill will be revealed at a later date, but the three major rock acts is a great start.

Organizers have also revealed a Rock in Rio USA pop weekend that will follow on the weekend of May 15 and 16 in Las Vegas, as well. Among the initial acts confirmed include No Doubt, Taylor Swift and John Legend.

Pre-sale tickets are already available with concertgoers already available to buy full weekend and single day packages. For details, check here. And stay tuned to the Rock in Rio USA festival website for updates on the lineup.
