Unless we are talking about Kool G Rap, or EPMD, 80's rap sounds very dated to me. It's kind like proto-hiphop for me. I really can see myself revisiting most of the music of that era.
Even classics like 3 feet high and rising. It's ok as sort of experimental energetic music, but in some ways it doesn't even sound like hip hop to me. mid to late 80's hip-hop was in some sort of late stage stripped down disco flux.
