The talented rapper and music producer Primary is prepping for the release of his new album. And as his pre-release track before the big drop, Primary has chosen the song "Poison" featuring a voice that hasn't been heard in Korean music for a while: Supreme Team's E-sens.

E-Sens was riding the wave of success as a member of one of the hottest hip hop duos in Korea, until he confessed to having smoked marijuana last year. He had then announced to the public his remorse and his indefinite departure from the music industry.

E-Sens' agency, Amoeba Culture made sure to point out that the rapper's collaboration on "Poison" isn't signaling the end to his ongoing hiatus. E-sens had just wanted to express his passion for music, expressing his state of mind and personality through the track.

Primary's full album will be released October 31st.
