In May 2015, at the height of their tour supporting The Hunting Party—their first album in seven years, reclaiming aggressive nu-metal with industrial edges after electronic experiments—Linkin Park headlined Rock in Rio USA, the American edition of the iconic festival launched in 1985 in Rio and expanded to Las Vegas with a rock and alternative focus. Their 90-minute set at MGM Grand Garden Arena, before a sold-out crowd, embodied the band's resilience amid internal tensions, where Brad Delson's riffs and Chester Bennington's emotive vocals fused into festival catharsis. This performance, part of the festival's U.S. push, underscored their genre-pioneering role, igniting the entertainment capital's arena.
