Dieuson Octave was born on 11 July 1997 in Pompano Beach, Florida. When filling out a registration form in Instagram, Octave called himself Kodak Black, which later became his pseudonym in the music industry.
When he was 12 years old, Octave used another pseudonym J-Black, under which he was accepted to a hip-hop group Brutal Yungenz. Later Black worked with another band, The Kolyons.
In December 2013, Black released his first mixtape Project Baby. A year later, another mixtape, Heart of the Projects, came out. The next mixtape Institution was recorded in 2015.
In October 2015, Canadian rapper Drake uploaded a video, in which he danced while listening to Black’s song "Skrt". This immediately made Black popular and brought him his first professional contract with Atlantic Records. Unfortunately, shortly after signing, Dieuson was arrested and charged with robbery and other crimes. Later he was released.
In May 2016, Octave participated in the recording of French Montana’s single "Lockjaw", which made it to the 23rd place of Billboard Hot R&B/Hip-Hop Songs chart. Before the month was over, Black and his fellow rapper Lil Uzi Vert announced going on a national tour called "Parental Advisory Tour". However, Vert had to go alone because Octave was arrested again. This time he was charged with an armed robbery.
