N.W.A. lost two members — Arabian Prince and standout MC Ice Cube, who then engaged with a heated on-wax war with the crew — but that didn't slow their roll. Their sophomore LP, Elif4zaggin, was a watershed moment. Dre's beats were bigger, crisper, more dramatic, more Compton, more gangsta, and really more "Dre" than ever. His signature sound had truly emerged (you can even hear the first traces of G-Funk on this album), and hip hop would never sound the same.
