More than any other rapper, Dr. Dre was responsible for moving away from the avant-noise and political stance of Public Enemy and Boogie Down Productions as well as the party vibes of old-school rap. Instead, Dre pioneered gangsta rap and his own variation of the sound, G-funk. BDP's early albums were hardcore but cautionary tales of the criminal mind, but Dre's records with N.W.A. celebrated the hedonistic, amoralistic side of gang life. Dre was never much of a rapper -- his rhymes were simple and his delivery was slow and clumsy -- but as a producer, he was extraordinary. With N.W.A. he melded the noise collages of the Bomb Squad with funky rhythms.
