Korland KJ Sims was born in Vallejo, CA on May 19th, 1994. After playing saxophone and piano for a couple of years, and also participating in a hip hop dance group, he became very serious about hip hop music. In 2006, at the age of 12, he formed the hip hop music group Chrome Cats, which also included his sister, cousin, and two of his sisters friends. He wrote over 20 songs that summer but only had the chance to record a few. After the summer ended, it was harder for him and his sister to team up the other members in the group due to school and schedules. So Korland continued writing and recording songs with his sister.
