Back Koo Young

Back Koo Young is a South Korean choreographer, dancer, and teacher who has shaped K-pop performance across SM Entertainment's roster and the international dance studio circuit. Known professionally as KOOYOUNG BACK on the 1MILLION Dance Studio artist roster, where he is affiliated with the V1LLION crew, Back has built a career at the intersection of idol choreography and dance education. In 2011, he was documented as a choreographer for TVXQ's "Before U Go," and during that period he conducted workshops in London and Paris teaching choreography from SHINee's "Lucifer." His trajectory from SM Entertainment backup dancer to choreographer reflects a common pathway in K-pop production, where performers transition into shaping the movement vocabulary of major acts. His ongoing presence at 1MILLION positions him as both a working artist and transmitter of K-pop dance vocabulary to international students.
