ghetto tech has been around for longer than half the current producers in techno! nothing new about it, some amazing stuff around, and some utter,utter garbage, like most off-shoots of techno, but certainly nothing new

and yeah ghetto tech isnt hard house beats with a compulsory "ghetto" vocal over it

proper ghetto tech check Slugo, Dj Hyperactive, Dj Funk, Skitzo etc etc
