American singer-songwriter Billy Joel will be performing his only European gig of the year in Cardiff on Friday, August 9 at the Principality Stadium. The stadium officials have confirmed that the roof will be closed for the concert, ensuring fans stay warm and dry. Gates open at 5pm and resale tickets are available starting at £115. Road closures are expected in Cardiff for the event. Billy Joel joins other stars who have performed with the roof closed, such as Taylor Swift, Bruce Springsteen, and Pink.
