IMO gangsta rap was never done in the east, so Big L, Biggie and other east coast legends can easily be left out. I think gangsta rap originally was and still is more LA / Sacramento based and Luniz from the bay area, Operation Stackola and thiiit.
Oh, and you can't forget this. Cash Money before it became old birdman pretending that he isn't 40 and drugged-up coked out weezy singing through an autotuner while some slut blows him in the studio.
