Primary has revealed the music video teaser for one of many collaborations on his upcoming album.

The producer worked with Supreme Team's E-Sens for "Poison", E-Sens' first project since his marijuana controversy last year. The song will be released on the 24th before Primary's first full-length album comes out on October 31 KST.

Agency Ameoba Culture stated, "During his [hiatus], E-Sens has spent his time producing here and there. This track includes his state of mind as well as his real personality, and through Producer Primary, E-Sens' true character will be revealed. Though E-Sens has not ended his hiatus for his own album promotions, he wanted to show his [passion for music], so please refrain from [hurried discussions about his return]."
