Twenty One Pilots is a pop duo formed in 2009 by lead vocalist Tyler Joseph and former members Nick Thomas and Chris Salih who eventually left in 2011. Josh Dun came after the former members left and the two everyone knows as Twenty One Pilots. The pair built an enormous regional following across Ohio and the midwest, spurned on by constant energetic touring as well as shrewd use of interactive social media and reaching out to fans on a grassroots level. The group self-released two albums of their rap-infused high tech pop, twenty | one | pilots in 2010 and Regional at Best in 2011. The group also gained popularity through publicly releasing a series of videos made by their friend Mark Eshelman. In 2012, the group signed to Atlantic Records subsidiary Fueled by Ramen, releasing the Three Songs EP in the summer of that year and working with Adele producer Greg Wells on their debut album for the label Vessel. Vessel saw release in January of 2013 and the band had international touring scheduled deep into the year in its support. Recently, the duo have been working on their newest album, Blurryface, and becoming more involved and interactive with their fans. Blurryface was released May 19th, 2015.
