Foo Fighters will make a surprise one-off appearance as AC/DC's opening act on 8 September at The Dome at America's Center in St. Louis, Missouri, stepping in for The Pretty Reckless. The special guest slot is a brief detour from Foo Fighters' own "Take Cover" global stadium tour and brings together two of rock's biggest live acts for a single night, with tickets already on sale via LiveNation.com.

Frontman Dave Grohl explained the personal significance of the pairing, recalling how AC/DC's 1980 concert film "Let There Be Rock" first exposed him to live rock performance at age eleven and shaped his approach to performing ever since. He described the show as "literally a dream come true," noting it marks the first time his band has shared a stage with AC/DC since that formative experience, while also recounting an earlier story of meeting the band via a dinner arranged through Paul McCartney.
