Eazy-E was a Kelly Park Compton Crip during his teen years, and he openly associated himself with other crips and crip sets. He sold drugs during his early teen years and then parlayed the money he made into a hip hop enterprise. He is widely regarded as one of the founders of the gangsta rap sub-genre and initially rose to fame as the founder and member of the group N.W.A., but later achieved critical and commercial success as a solo artist. Eazy-E's vocal style was marked by his youthful, high-pitched voice and his lyrics focusing on the elements of urban street life such as guns, drugs, relations between residents and the police, and sexual activity. He had also for some time hosted a hip-hop radio show on Los Angeles-based radio station KKBT.
