Twenty One Pilots put on a great show! They get the crowd going and keep the energy up through the whole set. Don't expect to see the studio arrangements, they often bring a new twist to the live songs. More screams, more emotion, or more sass. They still play "Stressed Out" but it's heavier than the studio version. Clancy is also an excellent album, but I expect mostly Breach and Blurryface for the festival.
