SAINt JHN is the shadowy, slow jam-oriented recording alias of Brooklyn native Carlos St. John. A rapper, singer, and songwriter, St. John kick-started his career during the mid-2010s by co-composing material for Kiesza ("Bad Thing," "The Love," "Piano"), Nico & Vinz (the single "Praying to a God"), Gorgon City ("Doubts"), and Usher ("Crash"), a sequence of advancements catalyzed by industry veteran Zach Katz, who had heard an early song St. John granted to a fellow fledgling artist. As St. John continued to rack up songwriting credits for other artists, he started issuing his own material independently in 2016. Among the tracks that caught on most were "Roses" and "Reflex." "3 Below" and "Some Nights" followed in 2017, the year he also co-wrote "Helicopters/Beware" for Jidenna and "Can't Wait" for dvsn. St. John's own "I Heard You Got Too Litt Last Night" was released in 2018.
