Who said that?
The only Gangs with DIRECT ties to HipHop are The Black Spades
and the Peacemakers

Skulls and Nomads have nothing to do with early HipHop
Man I'd have to dig it up but it was a doc about Bronx gangs in the 70's they skirted the issue of them having beef with the Spades as being a Black vs. PR thing and they said they used to throw parties and I forgot how the chick being interviewed put it exactly but she said Hip_hop as those Skull parties was were Rap was created, Granted as Disco died out Hip-Hop probably started being played but low key the Skulls didn't fukk with Black people like that.
Even I lived in the Bronx there were Latin Kings and they didn't fukk with non hispanic Black people but they didn't green light Black people they way Essays in LA do.
It was the same insinuation during the blackout of '77 where they said all those turntables and records were stolen and that created Hip=Hop or at least scratching. Grand Wizard Theodore ADOS ( I think) ( who claimed to create scraching said he got his equipment off of gang nikkas selling records ( he didn't say which gang though)
