17. Kamaiyah, 'A Good Night in the Ghetto'
On her precise and poised debut mixtape, Oakland's Kamaiyah moves easily between the sounds of her native Bay Area, classic G-funk and the electro boogie that came out before she was born. Rapping over beats full of fat bass, wet synths, and tinny, classic-sounding drum machines, she's a calm, unflappable rapper, springy and declarative, whether savoring her new levels of success ("How Does It Feel"), partying until dawn ("Ain't Goin' Home Tonight") or playing the field ("Niggas"). Song after song accomplishes everything it needs to within three minutes, small, ebullient get-togethers that show remarkable power in their concision. E.L.
