Formed in 2009 by high school friends Tyler Joseph, Nick Thomas, and Chris Salih,Twenty One Pilots built an enormous regional following across Ohio and the Midwest, spurred on by constant and energetic touring, shrewd use of interactive social media, and connecting with fans on a grassroots level. The trio self-released their eponymous debut album of rap-infused, high-tech pop in December 2009 before Thomas and Salih left the band in 2011. Frontman Tyler Joseph recruited replacement drummer Josh Dun and Twenty One Pilots continued as a duo. Later that year, second album Regional at Best surfaced, the first with the new lineup. In 2012, they signed to Atlantic subsidiary Fueled by Ramen, releasing the Three Songs EP and working with Adele producer Greg Wells on Vessel, their debut album for the label. Vessel was released in January 2013 and featured the platinum singles (Holding on to You) (House of Gold) and (Car Radio). For the recording of their third album, Twenty One Pilots opted to work with various producers on an almost song-by-song basis. Recruiting Ricky Reed, Mike Crossey, Tim Anderson, and others, this process took them to studios throughout Los Angeles and London. After a period of silence, during which time fans pieced together clues and theories about the group's next release, Twenty One Pilots emerged in 2018 with the single (Jumpsuit) b/w (Nico and the Niners) the first offerings from their fifth LP, Trench. Both the single and the album managed to crack the charts, with Trench rising to number one on Billboard's alternative rock album charts. Two years later, the band's non-album single, (Level of Concern) topped both the rock and alternative singles charts and they ended the year with the holiday cut (Christmas Saves the Day). (Shy Away) the first glimpse of Twenty One Pilots' 2021 LP Scaled and Icy, earned them another number one. Recorded long distance while Joseph and Dun were hunkered down during quarantine in their respective homes, the album set aside the weighty mythologies of previous efforts and focused on simpler emotional themes related to functioning in a world during a global pandemic. On February 15, 2021, Joseph uploaded an image to his Instagram story, with the 23rd letter of the Greek alphabet, psi, over his right eye. With the release of the lead single for Scaled and Icy, (Shy Away), two months later, this was revealed to be the band's new logo.
