Xdinary Heroes Cancels “Summer Sonic 2026” Appearances Following Gun-il’s Departure

Xdinary Heroes will no longer perform at Japan’s music festival “Summer Sonic 2026.”
On August 13, “Summer Sonic 2026” announced via its official social media accounts that Xdinary Heroes had canceled their appearances, just one day before the festival’s Tokyo event.
The organizers stated, “We have received a request from the artist’s agency to withdraw from the performances, and Xdinary Heroes’ appearances have therefore been canceled. We sincerely apologize to all the fans who were looking forward to seeing them perform.”
They added, “There will be no replacement artist following the cancellation of Xdinary Heroes’ appearances.”
