Heavydirtysoul

"Heavydirtysoul" is a song by American musical duo Twenty One Pilots from their fourth studio album Blurryface (2015). It was written by vocalist Tyler Joseph, who derived some of its lyrics from a poem called "Street Poetry" which he had written and published three years earlier. The track was produced by American record producer Ricky Reed and recorded at Serenity West Recording in Hollywood, California. As the opening track of Blurryface, "Heavydirtysoul" acts as the album's introduction, both musically and thematically. The song contains a self-referential statement where Joseph touches on the concept by candidly addressing its music with self-aware lyrics that give away his insecurities.

"Heavydirtysoul" is an intense, aggressive track in which the duo mix and move between several music genres. The song features high-speed vocals as Joseph rotates from complex rapping to melodic singing to falsetto screaming over soulful drumming by Josh Dun. Lyrically, "Heavydirtysoul" is about asking for help in defeating one's inner demons to become something greater. The song's lyrics convey an anthemic theme relating to self-discovery through being vulnerable.
