The stage is already being built for the Beyoncé gig this Saturday night at Croke Park.
Up to 75 thousand fans will see the show, which is one of the biggest productions ever hosted at the stadium, taking up half of the pitch.
The R&B star will play up to 32 songs in her set that lasts for around two hours.
forty thousand fans will also be at the Stone Roses in Marley Park on Saturday, and MCD estimates the two gigs will bring around €20M to the city.
Eamon Fox from MCD is warning fans not to bring iPads to Croke Park as the ban has come from Beyonce's rider.
