Columbus, Ohio duo, Twenty One Pilots, put on a breathtaking display at Dublin's 3Arena. The stage transformed as the show went on, filling with live flames and unique 2D visuals as the tone shifted throughout the performance. Mobile secondary stages in the crowd gave fans a clear view of the members no matter where they were in the venue. Support came from another duo, this one from Aukland, New Zealand, Balu Brigada.
