< Yi Jong Gong Gan > is a new work of “Be-Being,” a music group that explores the possibility of new performance art in collaboration with various genres by basing on Korean traditional music. “Yi Jong Gong Gan” is a story about the overlap or disappearance of time and space. It means the boundary of space where both death and life exist, making stories with sounds that linger between physical time and space, overlapping and disappearing. Jang Yeong-gyu, a member of movie music and UhUhBoo Project, directs the performance and music.
