In roughly a year, a long-vacant lot on the Strip transformed into sprawling festival grounds where some of the world’s most popular acts—including Metallica and Taylor Swift—convened over two weekends in May. The Rock in Rio USA Festival reportedly attracted more than 170,000 people, and, more importantly, brought some much-needed hope to the troubled North Strip. Though Rock in Rio won’t return until 2017, the site will continue to host festivals, concerts and sporting events. As for its name? It’s called the City of Rock. Starship would be proud.
