Hip Hop music is a Black American creation.
The foundation is Hip Hop can be traced to the Blues, to Muhammad Ali's promos, to James Brown's funk, to Gil Scott Heron and The Last Poets.
All the other groups of people that try to claim they participated in the creation Hip Hop music are full of shit.
Creation of an entire genre of music takes place over generation. It's not an emergent phenomena. The seeds are planted over time until a generation sprouts, taking all that came before them to become a tree.
You can look at the sample history of early Hip Hop music and see what was being sampled it is predominantly and overwhelming Black American music.
Other groups try to take credit for Hip Hop because it's probably the most genius artistic movement ever. It absorbs and swallows every genre. It is almost has no stylistic markers at this point.
But at the end of the day, Hip Hop is Black American, just because some Latinos or Caribbeans participated in it in the early days, doesn't mean their culture created it. White people participated in the early days of Hip Hop too. Shit, motherfuckers like Kraftwerks definitely influenced the electro sound of Newcleus and Afrika Bambatta. Them White folk singers in the hills and shit were rapping as early as the 1930s.
We ain't saying White people is Hip Hop founders are we?
Hip Hop music is Black American as fuck.
Everyone can get the fuck on, I'm tired of hearing about this shit.
"We were there too..."
Then where the fuck is the sonic influence? Nobody was rapping over no damn Merengue huh? Lol you fucking right.
These motherfuckers don't even got linguistic influence. All the slang is rooted in Black American jazz and funk culture.
Black Americans need to stop including motherfuckers that ain't have shit to do with shit in their cultural origin stories just to be nice.
