Came here to say this. Richmond Roulette is my favorite bay area rap album ever.
Also a big Cold World Hustlers fan here. In my opinion E-Sic is one of the dopest rappers to ever come out of the bay and sorely underrated.
I like a good amount of songs by 3x Krazy but I'm not the biggest fan to be honest.
IMP
RBL Posse
Young 'D' Boyz
Would round out my top five probably.
I guess some of those would be more considered duos but whatever.
I'd have too many honorable mentions to even start listing them if we are talking about groups from the "golden age" of bay rap.
I fucks with Main Attrakionz heavy for a group from these days.
