It’s safe to say that Twenty One Pilots have a hardcore fan base, as thousands of fans camp out to get tickets to their shows. The alternative hip-hop duo earned their first No.1 album last year on the Billboard 200 chart, with their fourth studio album, Blurryface. The duo success began with the collaboration of Tyler Joseph and Josh Dun, and in 2009 they released their self-titled album. Twenty One Pilots continues their success selling out shows with their Blurryface Tour. For more information on their Zoo Amphitheatre show, visit thezooamphitheatre.com.
