You can add the inaugural Rock in Rio USA Festival to your 2015 music event lineup. Announced last year with the names Metallica and Linkin Park attached, talent has been steadily increasing since the fest's original announcement.

The Rock in Rio USA Festival will take place over two weeks in May with designated rock and pop weekends. The rock weekend will take place May 8 and May 9 in Las Vegas.

The May 8 bill will feature a more alternative-leaning lineup with No Doubt, Mana, The Pretty Reckless, Foster the People, Gary Clark, Jr., Bleachers and Saints of Valory among those playing. For those looking for a harder edge, May 9 has Metallica, Linkin Park, Rise Against, Hollywood Undead, Deftones, Sepultura, Coheed & Cambria and Of Mice & Men all part of the lineup.

The pop weekend May 15 and 16 will feature such names as Taylor Swift, Bruno Mars, Sam Smith, Ed Sheeran, Jessie J, John Legend, Joss Stone and more. Organizers are also adding stages for electronic artists on both weekends along with a variety of other attractions.
