There are many groups in Hip Hop who were on the cusp of “making it big” and becoming household names.
There are even more who were incredibly influential and developed some of the techniques that became part of the blueprint that later groups benefitted from greatly. The Funky 4 check all of the above boxes and K.K Rockwell, Keith Caesar, Rahiem and Sha Rock were one of the first Rap groups formed at Hip Hop’s inception. M.C. Jazzy Jeff and Lil Rodney joined later and were part of a personnel change that would rename the group The Funky 4 Plus One.
