as for the vibe...during the late 80s/very early 90s...there was a lot of consciousness in hip hop...cube somewhat moved from the gangster shyt to being more “woke” (the term is cliched but I’m using it for lack of a better phrase)...I want to say he even had ties w/ the nation back then if memory serves me correct...it was in the music...in the attire (african medallions etc.) and in a lot of movies that dropped during the early 90s as well...the music/culture took a major shift tho toward gangster music en masse...especially on the east coast (it was already prevalent on the west)
To reply to the next part you wrote.
It's interesting because it's like Ice Cube was actually affiliated with Nation of Islam - but while others wore the symbols - he stayed hip hop in his attire. I mean the classic, black gear, sweaters, and Raiders gear.
So what I'm getting from this is that on top of the album being great music wise - it actually shifted Hip Hop culture at that time.

"look at all this classic shyt". It was considered normal. It was all we knew. But if you look back at 1991 alone....this album, Cypress Hill, Digital Underground, Ice-T, De La Soul, Black Sheep, AMG, DJ Quik, Geto Boys....and that's just off the top of my head....it's insane how much shyt came out in a relatively short time span. And not just that year, year after year all through out the 90's. And if I sat here and thought about it there's probably 10+ more albums that came out, that I can't remember right now.
it's a matter of fact
