Genre: Hip Hop/Rap
N.W.A (Niggaz Wit Attitude) was a South Central Los Angeles, California-based hip hop group widely considered one of the seminal acts of the gangsta rap sub-genre.
The original lineup consisted of Arabian Prince, DJ Yella, Dr. Dre, Eazy-E, Ice Cube, and MC Ren. Arabian Prince embarked on a solo career in 1989 and Ice Cube left in 1990 over royalty disputes.
Active from 1986 to 1991, the group endured controversy due to the explicit nature of their lyrics. They were subsequently banned from many mainstream US radio stations and even at times prevented from touring. In spite of this, the group has sold over 9 million units in the US alone.
