This might be painful for many people to hear but Twenty One Pilots is the biggest band in the world right now. Their 2015 album, “Blurry-face,” sold over one million copies and contained two Billboard top five hits. They’ve won several awards and they’re headlining Hangout Festival in 2017. And they’re bound to drop a new album. And it’s going to be huge because they are the hugest band in the world.
