Belgian pop duo Clouseau (brothers Koen and Kris Wauters, whose four-decade career has made them one of Flanders' most beloved acts) will perform at Brussels' King Boudewijn Stadium on 4 August 2027, becoming the first Belgian artists ever to headline the 55,000-capacity venue. The announcement, made on Flemish radio station Radio 2, coincides with the band's 40th anniversary and follows a record-breaking run of 137 sell-out shows at the AFAS Dome (a major indoor arena in Antwerp). The concert, for which a central stage configuration will allow capacity of nearly 60,000, marks a landmark moment for Belgian music, as the stadium has previously hosted only global acts such as the Rolling Stones, U2, and Beyoncé.
