Trench is the fifth studio album by American musical duo Twenty One Pilots, released on October 5, 2018, through Fueled by Ramen. It is the band's first studio album in three years, after the breakthrough of their previous album, Blurryface (2015). Recorded in secret during a year-long public silence, it is a concept album which explores mental health, suicide and doubt, themes prominently featured in the band's previous works, framed in the metaphorical city of Dema and the surrounding valley known as "Trench".The album is also the first release of the newly revived Elektra Music Group. The album was preceded by the release of four singles. The first two, "Jumpsuit" and "Nico and the Niners", were both released on July 11, 2018. The third single "Levitate" was released on August 8, 2018. The fourth single, "My Blood", was released August 27, 2018. To promote the album, the Bandito Tour began at the Bridgestone Arena in Nashville, Tennessee on October 16, 2018, and will continue through June 30, 2019, ending at the Nationwide Arena in Columbus, Ohio. Trench received acclaim from critics, who applauded its lyrical content, cohesiveness, and musical diversity; many recognized it as the band's best work thus far. It was also a commercial success, reaching number one in six countries, including Australia, New Zealand, Spain and the Netherlands and number two in several countries, notably the United Kingdom and United States.
