Lee Jae Jin
Lee Jae Jin (이재진) gives FT Island much of its low-end drive and vocal lift. FNC Entertainment's official profile lists him as the band's bassist and vocalist, a dual role that has kept him central to the group's sound from its 2007 debut through the current FaTe tour cycle.
That position matters because FT Island's longevity has always depended on more than one obvious star. Jae Jin helps keep the band tight onstage and musically balanced, especially as the group continues to work live-heavy markets across Asia. In a band built on chemistry, he is one of the reasons the music still lands as a unit.
