Even though they released only two albums and one EP, N.W.A. changed the gangsta-rap game forever, and N.W.A.: Greatest Hits is a one-stop collection of the L.A. group’s most electrifying songs. Tracks like “Gangsta Gangsta” crackle with Dr. Dre’s hyperactive wall of samples and DJ scratches, and a live recording of “Compton’s N the House” captures N.W.A.’s rowdy, defiant onstage energy.
