Early in a world war before the existence of DISCO, but then Hou did not now so crazy, so HIGH, at best, only some of the rhythm of some strong music, DJ then Hou just in the background of the program host, as if the host of the current radio.
In 1972, the Cherry Lips' "Play the Funky Muisc" was the real origin of DISCO. This style of music was immediately favored by the majority of young people at that time, and was later named "Funky", which is still very popular today. The "DJ" was transferred from behind the scenes to half behind the scenes, involved in some singing, music production and concert hosting and other behind-the-scenes work, can not be called a professional "DJ".
In 1981, a very familiar era emerged -- the era of breakdancing. The breakdancing style has continued to this day and has become a well known style. They are also derived from black street music and share the same characteristics - the "RAP" that was all the rage in '97. In 1981, the "DJ" officially moved from the backstage to the frontstage, and was responsible for selecting the right music from a variety of music to play for the customers. At that time, there were no CDs or LDs, DJs were just playing something called "Record", which is what we call a vinyl disk or record (we call it a platter in our profession).
