Too Short is actually one of the first California rappers period. And I’d say he’s just as influential as NWA maybe even more, he really created a distinct sound with Born to Mack which came out in 1987 a year before Straight Outta Compton.
Too Short, 4Tay, Hugh E MC and IMP were all happening the same time as Ice T and NWA.. so calling LA music "the foundation" is misleading and false. Just because the Bay chose independence first doesn't erase the pillars planted.
