King Iso

King Iso, born September 10, 1990, is an American rapper signed to Twisted Insane’s Brainsick Musik label. Before his recording career took off, he faced periods of homelessness and incarceration, experiences that heavily shape the raw, confessional tone of his lyrics.

He debuted with the album «The Insanity Plea» in 2015, followed by «Autophobia» in 2016, establishing himself within the horrorcore and underground rap scene associated with the Strange Music/Brainsick orbit. Tracks like «Jim Carrey» and «Twisted Thoughts» showcase his rapid, technically dense flow paired with dark, introspective subject matter covering mental health, trauma, and survival.

King Iso’s sound is marked by aggressive delivery, intricate rhyme schemes, and a willingness to explore uncomfortable personal themes, placing him alongside other underground horrorcore-adjacent artists. His catalog, including songs such as «Requiem» and «Chopped Liver», has earned him a dedicated following within independent hip-hop circles that value lyrical technicality over mainstream polish.
