BIGBANG, a representative K-pop group, will release their new song 'BiiiG' at 6 p.m. on the 19th to mark their 20th anniversary, their first release in four years. YG Entertainment revealed visual photos of the new track on the 13th through official SNS, completing the surrealist concept with restrained monochromatic tones. Against bizarrely fantastical backgrounds featuring twisted architecture and chimneys, members appear in refined suits, creating striking contrasts. BIGBANG has been building fan anticipation through diverse comeback teasings ranging from bold primary-colored posters to monochromatic artwork. Following the song's release, their 20th anniversary world tour 'BIGBANG 2026-2027 WORLD TOUR 〈XX: COSMOS〉' will launch in earnest, with performances planned from December 21-23 in Goyang, followed by a total of 33 concerts across 19 cities in North America, Europe, Oceania, and Asia.
