Profile
KAMDEN, also known as Kamden Na and Na Doo-bin, is the leader of AMPERS&ONE. Born in 2001, he grew up with Korean and American influences and became one of the band’s visible performance anchors.
Before debut he joined Wild Idol and competed on Mnet’s Boys Planet, ultimately finishing 17th. His television appearances and extended trainee period helped prepare him for live stages, rap and choreography.
