I've lived in Nigeria, and currently live in the States, No African Hip Hop artists except Akon is "BIG" in the states, and he grew up here, he's from Jersey City, his dad from Senegal, and he's travelled back and forth, as far as that goes, are there Nigerian Hip Hop CD's being sold over here? yes they are, usually they're bootlegged copies and you average bottlegger at the 7/11 out here is not going to have it on deck, you gotta look pretty hard to find it, you can find the stuff in little Nigerian stores here and there like at the West End Mall in Atlanta, where they sell Nigerian Food Products, Music and stuff of that nature, the thing is there are a lot of Nigerians living in the States in Atlanta, in Houston, TX, in NY, Philly (i think the biggest community is in Houston). a lot of them are cab drivers, and if you ask, some of them might be able to play you some 2face or some thing like that, if you ask a hip hop head who knows his shit out here, and that wasn't born yesterday about african hip hop, i believe MC Solaar would be the first and maybe only cat people remembered, maybe Prophets Of da City, and if you get one of the Def Jukie kids, they might know bout Cashless Society. Nigerian Hip Hop is only big amongst Nigerians in the States.
