IU is returning with the 10th anniversary single “Bbi Bbi.”

A 20-second teaser clip for the single was released online Sunday at midnight.

“Bbi Bbi” is an alternative rhythm and blues track -- a genre the solo artist is trying for the first time.

She worked on the lyrics of the song as well.

Prior to the teaser’s release, IU also unveiled four album-concept photos.

Following the album’s release, the singer will hold a concert tour starting end-October.

The tour kicks off in the South Korean coastal city of Busan on Oct. 28. IU will visit Gwangju, a southwestern city, and Seoul, in November.
