 SechsKies made their debut in April 1997 and quickly came to be seen as a rival of H.O.T, who had debuted a year earlier and were considered the first K-pop idol group to achieve mainstream recognition and success.Kim and Lee, who were the main dancers and choreographers, were largely responsible for some of the group's most memorable dances.Kim was not given many singing parts and was instead known for rapping in the Busan (dialect).
