EVOLUTION OF SOUND
Originally, EDM was surfaced by competing AM and FM radios as an emerging mainstream sound formerly underground and being experimented with by the "garage" and the quickly developing technology.
Barry White was the originator of the disco movement as he released the popular hits known as "Love's Theme and "Never Gonna Give Ya Up"
This disco era soon evolved into a more broad EDM era in its self as one giant culture that surrounded the idea of House music and its many sub-genres including acid house, dubstep, trap, progressive house, deep house, chill step, etc.
