<P> While attending Ohio State University, Joseph met Texas - born future bandmate Christopher "Chris" Salih at a party . Salih came from a musical background and consulted Joseph about starting a band . Impressed by the recording studio Salih had built in his house, Joseph agreed and began sharing his ideas . Just before their first performance, Joseph invited Thomas to join them as a bassist despite never having played the instrument before . In 2009, the group moved into a house of their own, where their first album was conceptualized and recorded in the basement . </P> <P> The band initially played for a wide variety of audiences at clubs and venues around the Columbus area . Playing at metal, hardcore, and electronic venues influenced Joseph to experiment with these disparate styles with his songwriting . To catch the attention of unfamiliar or disinterested attendees, the band began to experiment with costumes and on - stage acrobatics . </P> <P> Now going by "Twenty One Pilots", the group released their debut, self - titled album, Twenty One Pilots, on December 29, 2009, and began touring the rest of Ohio . Their initial marketing was very grassroots; Joseph's mother would stand outside of Ohio State University giving away tickets to his shows . During this time, the band participated in "Battle of the Band" contests at The Alrosa Villa and The Basement, important Columbus music venues . In 2010, the band posted two officially unreleased tracks to their SoundCloud account . These included a cover of "Jar of Hearts" by Christina Perri and a remixed interpretation of "Con te partirò (Time to Say Goodbye)" by Andrea Bocelli and Sarah Brightman; the latter would become the first song local drummer Josh Dun heard from the group . </P> <P> Salih left on May 8, 2011 to focus on work, and Thomas left the next month on June 3, 2011 to focus on schooling, both posting farewell notes on the band's official Facebook page . Before departing the project, Salih invited Guitar Center co-worker and friend of the group Josh Dun (former touring drummer for House of Heroes), to take his place in the band . Impressed by the band's potential and Joseph's creative vision, Dun abandoned plans to pursue drumming in Nashville and joined the project only a few weeks before Thomas left the group . </P>
