K-pop supergroup BTS will launch a monthlong cultural festival across Seoul, featuring a riverside drone show, media art displays and musical fountains, to celebrate its highly anticipated comeback this week after a nearly four-year hiatus. The septet announced on Monday details of its "BTS The City Arirang Seoul" project on Hybe's fan community platform Weverse. BigHit Music, the group's agency, has said the festival, set to run from Friday through April 19, was prepared in partnership with the Seoul metropolitan government to allow tourists and locals to "experience culture and art in a new way, and enjoy BTS' comeback." Related events will occur across the food, beverage and mobility sectors. The group previously staged similar "The City" festivals in Las Vegas in April 2022 and in Busan that October to mark its concerts in those cities, drawing massive crowds. To mark the Friday release of the group's fifth studio album, "Arirang," media facade shows will begin at 7 p.m. at Sungnyemun gate and Namsan Seoul Tower. A 15-minute drone show over Ttukseom Han River Park will follow at 8:30
