Guitarist and vocalist Yoo Hyun Sang and keyboardist Lee Yoo Jeong perform together as a music duo based in Jeju. The two first met as band members in 2023,

where they developed their musical chemistry, and later began performing under the name KITA & OLGEN after collaborating on original songs.

Centered on acoustic guitar and keyboard, their music blends folk-inspired sounds with a range of tones, expressing thoughts and emotions discovered in everyday life with sincerity

and restraint. Their songwriting is shaped by a habit of closely observing ordinary days and drawing stories from within those moments. Rooted in Jeju,

they continue to reflect the people and experiences of the island in their music while expanding their activities through live performances and recording projects.
