Its the south bay.
edit: Nah, really, its just that i dont see a solid grouping of artists that have come out of there. I know a few south bay artists, but i havent really heard of any that established their music with a distinct south bay sound. Its hard to compete with frisco (west bay), oakland (east bay), and vallejo (north/east) bay, and its not that i dont give south bay rappers a chance, its just that i dont hear much from that area, especially since my focus is on other areas.
edit: i voted that i dont "see sb artists in ya store"
