Other acts under the RAL umbrella included Redman, Onyx, Flatlinerz, Domino, Warren G and Jayo Felony. Def Jam also signed its first and only thrash metal band, Slayer, in 1986, and the band’s third and fourth albums were the only two Def Jam releases to be distributed through Geffen Records under Warner Bros. Records as opposed to Columbia/CBS.
As the decade drew to a close, the label signed Public Enemy, whose controversial lyrical content garnered the company both critical acclaim and disdain. Lyor Cohen became president of Def Jam/RAL in 1988, after winning a power struggle with Rubin, who would shortly thereafter leave the company to form Def American Recordings. Rubin would take Slayer with him to Def American in its initial stages.
