I never seen any of the other ones in stores, they might only be able to be found in Oakland if they are out at all. Sometimes rappers put a buncha album covers in their shit to make their inside cover look cool and make it look like they doing alot and making moves. Maybe they ain't out yet.
All I know is in J Stalins inside cover there are a couple upcoming projects that look real nice like the J Stalin & Beeda Weeda collabo album, I'd pick that one up real fast if it ever comes out, they are my 2 favorite New Oakland rappers that shit would be hella nice
