Twenty One Pilots is a duo Josh Dun and Tyler Joseph. The band originally started in 2009 but josh was addition in 2011 and has been playing ever since.
As many fans of Twenty One Pilots know Josh and Tyler never told the real story of how they both met. So, im going to tell you. Josh was invited to one of the concerts by one of the former band members of twenty one plots where he then met Tyler and they built a friendship.
Josh played in one show and since that day he became the official drummer for Twenty One Pilots.
They are not your average band because most bands beautify depression and suicide as for them they show their fans that there is an alternative and you can hear in their lyrics that they really care and want to change people's lives. Which is exactly what they do.
