BigBang Marks 20th Anniversary With a Spectacular Return… Releases New Song “BiiiG” on the 19th and Kicks Off an Epic Jamsil Project

The group BigBang (BIGBANG) marks its 20th debut anniversary with the release of the new song “BiiiG (Big)” for the first time in four years and four months, followed by a string of massive offline events and a mega-scale world tour aimed at filling the Jamsil area with excitement, signaling a flashy comeback from a K-pop legend.

A comeback after four years and four months, “BiiiG” that captures the identity of the trio YG Entertainment, through its official blog on the 10th, unveiled a poster for the new single and said BigBang will release the new digital single “BiiiG (Big)” at 6 p.m. on the 19th, a day that marks the group’s 20th debut anniversary. BigBang’s release of a new song as a team is about four years and four months after “Spring Summer Fall Winter (Still Life),” which swept the top spots on major music charts in April 2022. The poster released shows the members’ silhouettes against a dark background that is split by three lights—blue, red, and yellow. In particular, the track title “BiiiG,” which repeats the alphabet “i” three times, has sparked speculation that it symbolizes the current BigBang reshaped into a three-member system. The agency said, “It will be a song that shows BigBang’s present most clearly as it marks 20 years since debut,” and asked for anticipation.

The venue for the 20th-anniversary festival that will color Jamsil with BigBang Along with the single release, a large-scale offline project that fans and residents can enjoy together is set into motion. From the 14th to the 23rd, during the 10-day period, the Jamsil area in Songpa-gu, Seoul will host a lineup of festivities, including a media exhibition, photo zones, an MD shop, and a lighting event at Seokchon Lake. At the Art Hall on the 6th floor of Avenueuel, a media exhibition featuring the footsteps of the past 20 years will be held, hosted by MUT (Creative Mutt). On the 1st basement floor of Lotte World Mall, related MD shops and limited-edition desserts will be available. In addition, on the 5th-floor bridge connecting Avenueuel and Lotte World Mall, an experience event themed around “COSMOS” will operate, converting fans’ cheering messages into a space message (Arecibo code). Especially on the day of the debut anniversary at 8:19 p.m., a special lighting show will be turned on around the Dongho area of Seokchon Lake, delivering meaningful memories with a lighting concept modeled on the group’s official light stick, “Bang Bong.”

A 33-show world tour “COSMOS” aimed at going global For a long time, BigBang—known for representing the second generation of K-pop with its homegrown hip-hop-based producing skills and dazzling performances—will launch a large-scale world tour right after the new song’s release. Starting with “BigBang 2026~2027 World Tour XX: COSMOS (COSMOS),” which will be held at the main stadium of Goyang Sports Complex from the 21st to the 23rd, BigBang will connect with global fans across 19 cities around the world, totaling 33 shows, including North America, Europe, Oceania, and Asia. With its overwhelming scale, the tour is expected to add more locations later, drawing intense attention from music fans worldwide.
