A member of one of the original hip-hop crews, Treacherous Three, Kool Moe Dee later became a solo star in his own right in 1986 by teaming with a teen-aged Teddy Riley (later famed as the king of new jack swing) on the crossover hit “Go See the Doctor.” The single earned him a contract with Jive Records, for which he recorded three successful late-’80s albums, dominated by his skillful speed-raps. A long-running feud with LL Cool J — who stole his aggressive stance and rapping style, he claims — gained Kool Moe Dee headlines for awhile, but he began to fade by the early ’90s.
