The characteristics of a Sound Style at that time were an artist that belonged to a Sound. JUN 4 SHOT, CRISS, TRUTHFUL (a.k.a. STICKO) who were Junior and High school students started to perform. Afterwards, coming back from training overseas in the mid 90's, Mighty Crown's domestic activity got brisk. JUN 4 SHOT's classmate CHOZEN LEE who already was a DJ in the Yokohama and Tokyo area joined Mighty Crown. At dances (lives), with a RUFF and DIRECT style, they repeatedly trained themselves.
