Singer-songwriter Kevin Oh is getting ready for his debut.

The 26-year-old won Mnet’s music competition show “Superstar K” last year and will unveil his first single next week, according to his entertainment agency CJ E&M on Thursday.

Produced in collaboration with hip-hop artist Primary, the upcoming track “Yesterday, Today, Tomorrow” is expected to boast Oh’s soft ballads which allowed him to rise to the top in “Superstar K.”

Primary has collaborated with some of the biggest names in Korean hip-hop, including Zion. T, Gaeko and Dynamic Duo.

After taking home first prize on the seventh season of “Superstar K,” Oh has mostly stayed out of the public eye, with the exception of contributing to the soundtrack of tvN’s drama series “Dear My Friends,” which aired earlier this year.

The single “Yesterday, Today, Tomorrow” will be available on local music sites from Nov. 16.
