N.W.A, the unapologetically violent and sexist pioneers of gangsta rap, are in many ways the most notorious group in the history of rap. Emerging in the late '80s, when Public Enemy had rewritten the rules of hardcore rap by proving that it could be intelligent, revolutionary, and socially aware, N.W.A capitalized on PE's sonic breakthroughs while ignoring their message. Instead, the five-piece crew celebrated the violence and hedonism of the criminal life, capturing it all in blunt, harsh language. Initially, the group's relentless attack appeared to be serious, vital commentary, and it even provoked the FBI to caution N.W.A's record company, but following Ice Cube's departure in late 1989, the group began to turn to self-parody. With his high-pitched whine, Eazy-E's urban nightmares now seemed like comic book fantasies, but ones that fulfilled the fantasies of the teenage white suburbanites who had become their core audience, and the group became more popular than ever. Nevertheless, clashing egos prevented the band from recording a third album, and they fell apart once producer Dr. Dre left for a solo career in 1992. Although the group was no longer active, their influence -- from their funky, bass-driven beats to their exaggerated lyrics -- was evident throughout the '90s.
