Some really good points. Also some reaches. The Cam part is more ‘cool, small world’ coincidence. The Roc was off and running before Cam
But I think you can close your argument with the Just blaze, Neptunes, and Kanye angle alone. That’s kinda crazy. Neptunes and just blaze first rap song a Mase song, and Kanye came under the wing of D Dot, who executive produced Mase debut album
Edit: D Dot also produced on ‘Where I’m from’ on Vol 1, which came out a week
after Harlem World
As far as the south thing didnt jay do money ain’t a thing first? (Edit: no, that was 98). But jay had a southern artist on Vol 1 (edit: no, I’m thinking of 2 Short). Well I don’t think that was the first east-South collab. I remember Outkast went on a run with Raekwon and slick Rick (edit: nope, Skew it on the bar b was 98. Art of storytelling was 99).
