In 2021, a world music player LK9(Lee Kyung-gu) released Identity, a performance in which he combined Korean musical elements from his own music with world music instruments to create sounds that transcend borders. This concert consists of creative music expressing the artist's experience about his own body. For his work, sensuous computer beats are used to express our inner emotions as well as make anyone enjoy music. In addition, various instruments uniquely combined by LK9 are added to make the performance even more impressive and give the audience the pleasure of seeing and hearing. Through this the performance shows how it can be expanded to a convergence performance that is based on traditional music.
