Some rappers from the earliest stages of hip hop that hip hop fans wouldn't mind hearing from again are Afrika Bambaataa, The Sugarhill Gang, Grandmaster Flash, Slick Rick, Doug E. Fresh, and Kool Moe Dee. Popular 1990 rappers that caused quite a stir in their day that could easily come back and be welcomed with open arms are rap groups such as Public Enemy, Bone Thugs-n-Harmony, Wu-Tang Clan, and The Fugees.
Last but not least, another "Old School Rapper" that can certainly make a comeback is LL Cool J. With decades of hits such as "Rock the Bells", "Jingling Baby", "Hey Lover", "Phenomenon", Luv U Better", many would find him to be just as proclaimed with his 2000 titled album, "G.O.A.T"- the Greatest of All Times. But if and when these "Old School Rappers" return, just as LL Cool J said in his year 1990 smash, "Mama Said Knock You Out"- DON'T CALL IT A COMEBACK, I've Been Here for Years!
