dubstep is a derivitive of dub being what people started calling the dub mixes of 2-step or Garage songs. dubstep in itself was not a music that was produced, just like dub or bmore, rather a remix style that eventually producers started creating music that mimmicked what the remixers were doing. dub mixes (taking out the vocals and only using cuts, and then accentuating the bass and kick drum) was an essential mix on any 12 inch in the 80s. you had radio edit, club mix, dub mix, acapella, and if you were special you also had a 10 minute shep pettibone mix (anyone my age who remotely listended to funk or pop knows shep pettibone). but yes as per chev its hard to imagine dubstep without sub bass (which i only found out what the hell people were talking about when seeing chevs commetns of peoples tracks he he) havent checked it yet haydos. this w/e hopefully. though as you know i aint much of a dubstep dude
