TIME TRAVELER, an album release to mark the 25th anniversary of Korean singer Seotaiji, is a personal brand project that thoroughly represents his musical world and identity since his debut. Seotaiji has released numerous pioneering songs that have had a massive impact on music trends in Korea. From this point, he is portrayed as a time traveler who embarks on musical journeys through a black hole that transcends time and space. The album design was visualized as Oopats (Out-Of-Place ARTifactS) and was also applied to performance design and other design applications.
