The only gangsta-tech artist I know is Matt K.
And personnally, I like this kind of stuff.

The "gangster" image is getting more and more obvious in the electronic music (IE : Eskimo (Psy-Trance artist)). I don't know if it's for attracting people for an another sub-culture or whatever but in my opinion, we shall be able to produce/spin/listen whatever we want without being categorized as one type of person.
