In class we listened to some early hip-hop from the 80's that I  liked because of its simplicty in terms of the beat and/or the limited presence of other effects like in Slick Rick Doug E. Fresh's La Di Da Di where it was a complete absence of machine/instruments and the beat was beatboxed by Doug E. (you wouldn't be able to tell the difference) and Rick's lone voice with straight calm/paced lyrics. In contrast, early hip-hop could also get in depth and detailed with lyrics  that were delivered with an amazing flow.
