I remember in 1980 the Sugar Hill Gang came out with their second single "Eighth Wonder." I remember Kurtis Blow coming out with his first single "The Breaks." I remember Grandmaster Flash and The Furious Five coming out with their first single "Freedom." Those singles were all hits where I grew up. Rap music was still in its infancy stage. In 1980 there were only a handful of rap songs being played on the radio, because at that time there were not that many rap songs in existence.
Then 1981 a few more rap groups started releasing singles. There were groups such as the Treacherous Three, Dr. Jeckyll & Mr. Hyde, Funky Four plus One. Those rap groups were more or less a continuation of the rap groups that came out before them. Up to that point, rap styles hasn't really changed.
In the same year 1981 hip hop music was about to go through a major change. In 1981 the group Kraftwerk had released the singles "Numbers" and "Computer World." Those two songs "Numbers" and "Computer World" was our introduction to this new electronic style music. Both of those songs were huge hits in my hometown. Also, during this same era Kraftwerk had released a single called "Trans Europe Express." These songs were hits in Hip hop for hip hop fans. The Kraftwerk sound could be described as computerized, electronic, or robotic. This new electronic sound was such a big thing in the hip hop community that it had spawned off a whole new era and sound in hip hop music. This new electronic sound was the primary style of hip hop music for the next two or maybe three years
This electronic hip hop spawned off many songs and new groups during this brief era in hip hop. Some of those songs included "Planet Rock" by Afrika Bambaataa and the Soul Sonic Force. There was "Pac Jam" by the Jonzun Crew. There was "Looking For The Perfect Beat" by Afrika Bambaataa & the Soul Sonic Force. There was "Play At Your Own Risk" by Planet Patrol. There was "Jam On It" by Nucleus. There was "I.O.U." by Freeez. There was "Pop Goes Your Love" by Freeez.
There were many more electronic style hip hop released in this brief era of hip hop. This electronic era of hip hop started around 1981 and continued to maybe 1983 or 1984. I myself now call that particular music electronic hip hop. That's just the name I use to describe that particular music. At that time I seem to remember that we didn't have a name for that type of music. I do remember that it was the most common music used for break dancing during time.
