Sleeping Bag Records. 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 via 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 and the rights of its Def Jam albums with him to Def American in its initial stages.

PolyGram acquired an additional 10% in Def Jam, further strengthening its ownership of the label. Shortly thereafter, Rush Associated Labels were renamed to the Def Jam Music Group. The label remained profitable as its veteran star LL Cool J released his successful album Mr. Smith in 1995, a return to the rapper's original credibility following the fallback of his 1993 album, 14 Shots to the Dome; his last album under the Def Jam/Columbia partnership. The label later signed Foxy Brown, whose debut album, Ill Na Na (1996) became a platinum seller in 1997. Def Jam followed up with its then-new R&B
