Large-scale digital billboards located along the Las Vegas Strip feature displays welcoming BTS. (Hybe) BTS transformed Las Vegas into a massive red-hued celebration of “Arirang” ahead of the group’s concerts in the US city, launching a large-scale citywide campaign tied to its ongoing world tour.The group kicked off “BTS The City Arirang — Las Vegas” on May 20 ahead of its four concerts at Allegiant Stadium, held May 23-24 and 27-28. After turning the city purple during its 2022 Las Vegas concerts, BTS returned this year with a citywide takeover centered on red — the key color of its fifth studio album “Arirang.”One of the campaign’s biggest highlights was an activation at Sphere, the world’s largest spherical performance venue. On concert nights, the venue’s massive exterior displayed visuals inspired by Korean traditional imagery and the album’s concept. The Sphere, lit up in red as well as a monorail wrapped in red visuals and the slogan "What Is Your Arirang?" can be seen at Las Vegas. (Hybe) The Sphere featured silhouettes of BTS holding traditional Korean lanterns as well as giant bell imagery — a nod to the album’s sixth track “No. 29” that incorporates the audio recording of the Sacred Bell of King Seongdeok. The bell imagery was accompanied by sound vibration waves that later spread across the structure before the album logo appeared, followed by the messages: “What Is Your Love Song?” and “What Is Your Arirang?”Across the Las Vegas Strip, landmarks including the High Roller observation wheel, the Eiffel Tower at Paris Las Vegas and the Las Vegas Gateway Arches lit up in bright red. More than 30 digital billboards throughout the city displayed welcome messages for BTS and the “Arirang” tour.
