Jam-Master Jay used to say 'it ain't hip hop if there ain't no DJ.' He's a legendary figure in hip hop, but I respectfully disagree with that statement.
Well, of course, because hip hop culture is more than just the DJ and MC.
We can respect/honor/revere the pioneers/icons of the genre and their particular definitions of what the genre is, but it doesn't automatically make it gospel
But hip-hop music is broad and comprises more than just rap music. That's what allowed the genre and culture to grow in the first place--the experimentation, innovations.
It definitely is gospel when the trinity of hip hop pioneers (Bam, Flash, Herc) agree on just what hip-hop music is.
These people are respected artists and, in the case of KRS, a hip hop legend--but they obviously have very selective memories and have chosen to ignore the genre's origins.
So what I'm saying is, even great artists have biases and their particular views of a certain genre are not unquestionably the gospel of said genre.
Yes, artists aren't necessarily historians and can be totally biased to work in their favor. There's always going to be that ignorance around. For example, what's rampant in hip-hop is this self-hype of "I'm the greatest rapper in the world" or Diddy claiming he "invented the remix," silly stuff like that.
However, it is gospel when the founders all agree on the diversity of hip-hop music and are saying that it's more than just rap music. That's the root.
Can we really argue with living primary sources like this, the architects of it all?
