— BTS’ big reunion era is about to arrive in New England as the group prepares to bring its “ARIRANG” World Tour to Gillette Stadium on Aug. 5 and Aug. 6. The Gillette Stadium dates also arrive on the heels of an announcement that the band won’t be submitting music for consideration at next year’s Grammy Awards. Are BTS’ Foxborough concerts sold out? StubHub remains one of the largest secondary marketplaces for BTS tickets. That decision has only amplified conversation around BTS’ and the group’s latest album, “ARIRANG,” while the world tour heads to sold out stadiums across multiple continents.
