Cormega gives a history lesson:

"I didnt get in Trag DVD cause it was some white dude
who NEVER beeen to QB tellin the story!
As far as Trag on some real shit before me????
(...)If it was streets I disagree though Trag did grow up
going threw shit and if its rap
then I dont even have to respond
go back to PHD album (1991)
listen to my verse I was rapping about guns" My device has
a long clip with infra red light" (Goodfellas had the mac 11 with infra)
I was rappin bout drugs "Hotday supplys the base like a drug dealer"
"Dont front on me shorty ya mans workin for me" "I leave the fuckin
mic smokin like base pipes" "Kick down doors like TNT in a drug bust" (cause I was the ONLY rapper sellin
at that time) I was rappin about jail "I set it off like a soldier in
4 main" and actually I sent Trag a subliminal "Cormega can never
be imitated Motivators fear the poetry I generated" (we had a rivalry
back then but we never batted) and we always had respect for
each others skill thats why today me and Trag are so close
I can honestly say hes one of my best friends out of all the rappers.
Anyway like I said I was the 1st hard street rapper in QB In 91
Trag was a positive pro black rapper and Mobb Deep were
called "The Poetical Prophets" and Nas was lyrical. Actually Poet from
Screwball was rappin street before them too! I was a pioneer
I was just rappin what I was living!"

It's not rare, I my have grabbed this from another blog actually (though I own an original as well on wax) but here is what Cormega is talking about:

PHD ft. Cormega- Set It (1991)

And fuck whoever here likes club rap music... this is that hard shit from QB for your whip... not that new Mobb Deep garbage.
