Rock in Rio USA was a music festival held in Las Vegas, Nevada from May 8–9 and 15–16, 2015 at the MGM Resorts Festival Grounds on the Las Vegas Strip in Paradise, Nevada. The event was conceived as an American version of Rio de Janeiro's Rock in Rio festival, and was a partnership between SFX Entertainment, Eike Batista's IMX, MGM Resorts International, Yucaipa Companies, and Cirque du Soleil Entertainment Group. The event was hosted at a new open-air venue neighboring the then MGM-owned Circus Circus Las Vegas, which was developed by the consortium. It shared a similar format to its Brazilian counterpart, with plans to host at least 120 acts across two weekends oriented towards rock music and pop music respectively.
