Tyler Joseph is the singer and frontman of Twenty One Pilots, and Vessel is the duo's 2013 album, their major label debut. Short behind-the-scenes style clips of his voice have circulated among fans online, separate from the polished album tracks. This vocal warmup excerpt spread as a small, shareable moment because it shows the preparation behind the singing heard on that era's songs. It remains used by fans who collect live, acoustic and unreleased-feeling Joseph vocal moments alongside the official releases.
