Ray Ronald Chester Jumalon (also known as Rei Jum) is well known by his unconventional, dreamy and nostalgic elements of his music. His interest in music production ignited at the age of 15 when he knew that Adam Young (aka Owl City) started making music in his parents' basement. Even though he lack the resources, he started composing music with his phone and borrows a laptop every friday night. He records his vocals with a cheap microphone and also in his phone until today. He left his music production career and focus on his academics and arts when he entered first college. Later on, he decided to go back to music production by taking advantage of the vacant time during the pandemic. Chester met people who helped and collaborated with him which stretched out the scope of his music. He signed his first music contract at Dreamify Records and became it's official artist.
