After wrapping up their “Beautiful Night” promotions, B2ST’s Yang Yoseob is embarking on his solo career for the time being by unleashing his first solo album ‘The First Collage’ featuring the title song, “Caffeine”.

For his solo debut, Yoseob teamed up with his bandmate Yong Junhyung, who has set the concept of the new record and participated in the overall producing. Yoseob’s title track “Caffeine” compares a bad relationship to an addiction. The song is about man not being able to forget a past love, who keeps him awake like caffeine.

As B2ST’s main vocalist, Yoseob has already proved his musical talent by starring in KBS’ singing competition show “Immortal Song” and Korean musical “Gwanghwamun Younga” last year.
