<P> With the help of friend Jerry Heller, Eazy - E founded Ruthless Records on March 3, 1986 . Shortly afterwards, his group N.W.A released the Panic Zone EP . It contained the title track (Arabian Prince), "8 Ball" (Eazy - E), and the well - known "Dope Man" (Ice Cube). Despite its popularity, "Dope Man" was never released as a proper single . In a way, the song set the bar for later hits with its profanity - driven lyrics . </P> <P> The group's debut album was released later in the year . It featured the Fila Fresh Crew and a young The D.O.C. The most popular song on the release was the famous track "Boyz - n - the - Hood". Although the track was written by Ice Cube, Eazy - E handled the vocals . </P> <P> A disagreement over money saw Arabian Prince leave N.W.A just before the release of their ground - breaking Straight Outta Compton . Eazy - E's friend MC Ren filled his place . Backed by hit singles such as the title track, "Fuck tha Police", and "Gangsta Gangsta", the album redefined hip hop genre and cemented the West Coast's presence in the nation's rap scene . </P> <P> Financial issues led to the break up of the group . Eazy - E remained the wealthy owner / manager of his Ruthless label . Ice Cube released a string of successful albums that included AmeriKKKa's Most Wanted and Death Certificate . Dr. Dre would go on to co-own Death Row Records with Suge Knight . </P>
