what about Coke La Rock from the south Bronx in the late 70's early 80's
He used to rock house jams, perform his songs, do freestyles and shit until a certain part of his show when he used to tell everybody in the audience to raise they hands in the air. Then he would pull his gun out and rob everybody in the party
does anybody remember the movie Wildstyle where Double Trouble came on stage with guns lookin like gangsta's that was 82/83
gangsta shit always been apart of Hip Hop, no one person invented it
