In September 2015, American pop-rock band Imagine Dragons—at the peak of the Night Visions Tour supporting Night Visions (2012)—delivered an exclusive concert for iHeartRadio Destination Unknown, a special series where artists perform in secret locations revealed only 24 hours in advance. Their 60-minute set, captured in high quality in an abandoned Las Vegas theater before 500 attendees, embodied the tour climax, where Wayne Sermon's guitar riffs merged with Daniel Platzman's drum power and Dan Reynolds' vocal intensity to spark euphoria. Featuring tracks like "Radioactive", "Demons", and "It's Time", this show highlighted their role as 2010s stadium pop-rock leaders, turning the derelict theater into a realm of collective triumph.
