Twenty Years, One Live Band: How BIGBANG Built 'XX: COSMOS' for the Stadium

Most anniversary tours look back. BIGBANG brought a band. When the group opened XX: COSMOS in Goyang in August, SBS reported, every song was played live by a band session led by Wow Jones, a musician whose credits include Usher, Post Malone and Rihanna. For a group whose catalog was built on tightly produced electronic hits, that is a choice about craft, not just nostalgia.

This is BIGBANG's first world tour as a group in nine years, according to YG Entertainment, and their first since 2017, per Rolling Stone. It is also, quietly, a lesson in how to rebuild a stadium show around the people who are actually on stage now: G-Dragon, Taeyang and Daesung.

The announcement: a festival stage

The tour was confirmed in the most public way possible. Forbes and Rolling Stone both reported that G-Dragon announced it from the stage at Coachella in April. "This is just the beginning," he told the crowd, according to Rolling Stone. "BIGBANG's 20th-anniversary world tour will begin this August."

Then came the anniversary itself. On August 19, the date of their debut, YG says the group held a free fan event at Yeouido Hangang Park in Seoul and released a new digital single, "BiiiG." SBS reports the song topped iTunes song charts in 24 regions. Two days later, the tour opened with three sold-out nights at Goyang Stadium, from August 21 to 23.

Craft decision 1: the members write the show

SBS, citing YG, says the members "personally participated in all aspects of concert production, ranging from the setlist and stage design to the overall direction." That matters more than it might seem. A twenty-year catalog is a puzzle: which eras to honor, which hits to rearrange, how to pace a night for fans who joined in 2006 and fans who joined last year.

The name explains the brief. "'XX' represents BIGBANG's 20 years since debut," YG writes, "while 'COSMOS'" is meant to "symbolize the cosmic connection linking the past, present, and future." In other words, the setlist is the concept.

Craft decision 2: a live band on every song

Playing every song with a live band changes how a pop show breathes. Arrangements can stretch. Intros can build. Tempos can lift with a crowd. It also raises the stakes, because there is less to hide behind.

That is what makes the choice admirable. A legacy act can play it safe with backing tracks and a greatest-hits reel. BIGBANG chose the harder, warmer version of their own songs.

Craft decision 3: a stage team with stadium credits

The production team is built for scale. SBS reports that Mike Carson, who directed the 2025 Super Bowl Halftime Show, and Es Devlin, who handled stage design for the closing ceremony of the 2012 London Olympics, both took part. These are people who design for the back row of the biggest venues in the world, and whose work is meant to be read from far away.

The tour's map shows why that matters. YG first announced 33 shows in 19 cities (Rolling Stone's April announcement listed 31), and its tour page now runs through February 2027, with a fourth Hong Kong night added on November 17. The Asian leg opened at the Taipei Dome. KStarTrend reports that those three Taipei shows, October 9 to 11, sold out and drew about 100,000 fans, the group's first Taiwan concerts in roughly ten years, and that the night opened with "FANTASTIC BABY." YG's tour page lists Bangkok on November 7 and 8, Kai Tak Stadium in Hong Kong from November 13 to 17, then Osaka, Nagoya, and Tokyo Dome from December 13 to 15.

ACROSS ASIA

This tour runs through some of Asia's newest giant rooms. The Taipei Dome opened in 2023; TWICE filled it for three nights this March, as we noted in our reading of the THIS IS FOR tour numbers. Hong Kong's Kai Tak Sports Park, home to the 50,000-capacity Kai Tak Stadium, sits on the site of the city's former Kai Tak Airport. It opened to the public on March 1, 2025, and is the largest sports venue in Hong Kong. A group that has been touring Asia for two decades is now filling stadiums that did not exist when its last world tour ended.

A fresh perspective: anniversaries as rebuilds

The easy version of a 20th-anniversary tour is a museum: the old hits, played the old way. XX: COSMOS is closer to a renovation. The members chose the setlist, a band plays every note, and a world-class stage team scales it to stadiums.

Applause, then, for a group that marked twenty years by making the show harder to do, not easier. The past is in the setlist. The present is in the band.
