LOL @ west coast rappers not listening to NY in the 90s
Snoop and Nas both talk about how they ran into each other in Cali in 1993 a whole year before Illmatic dropped and Snoop told him how dope he thought he was.
Rap nikkas from everywhere are more studious of the game than you think. Rappers from different areas of the country fukk with each other too and know who to holla at when they go to different cities. If you a rapper, you don't have an automatic pass just to slide through any city. Plus rappers always wanna go to the hood and get the insider experience when they go to different cities and states. Snoop said that he wouldn't go to NYC without hollering at the right nikkas. Case in point, rappers from my old hood in Lakeview in SF like Cellski know everybody in the damn industry and everybody fukk with dem when they come to the Bay from Curren$y to 2Chainz to Jeezy to Wiz Khalifa to Jim Jones etc. But you know that real street nikkas who rap don't be on TV everyday and dressing gay on that mainstream Illuminatti shyt.
You right that East Coast and Down South rappers used to slide through Cali all the time before they blew up. I read somewhere that Jay-Z tried to slip somebody his demo tape back in the early 90's at the McDonald's in Fillmoe in Frisco.
But some things were way too much of a coincidence too. Like Dre Dog a.k.a. Andre Nickatina from Fillmoe in Frisco came out with this song called "The Ave" that used the same exact Mtume sample as "Juicy" a whole year before Biggie and Bad Boy used it. Coincidence? I think not.

Big and Puff were out in the Bay at some point in 93' and heard the Nickatina joint on the radio or out somehwere and straight gaffled the idea and ran with it knowing that Bay nikkas don't be on TV and the radio nationwide like that
