Kim Yeon Gyu is a South Korean singer, dancer and member of ATBO (에이티비오). He graduated from Seoul Performing Arts High School.
Before debuting, he spent nearly a year as a trainee, including time at YG Entertainment where he was part of the audition show to select the members for what became TREASURE. However, he was eliminated in the latter stages and decided to leave the company.
In early 2022, he participated in the survival show “The Origin – A, B, Or What?” under IST Entertainment (IST엔터테인먼트) and ended up 7th place, qualifying to be a member of the show's project group.
He made his debut in July 2022 as ATBO's main vocalist with their first mini-album, "The Beginning: 開花".
In September 2024, ATBO will join JUST B to form a special project group called THE CREW ONE (더크루원) to participate in the survival show "Road to Kingdom Season 2".
