Death Rap is a style of rap thats lyrics and rhymes derive from the intense lyrics of Death Metal and Goregrind Metal.
Death Rap roots are also related to the violent and explicit lyrics of Gangster Rap, however Death Rap lyrics are more over the top and violent than those of Gangster Rap.
A very early example of the Death Rap genre is the late Biggy Smalls a.k.a Notorious BIG.
More modern day examples include east coast mc's: Necro and Ill Bill.
