In the late-'90s, Mark The 45 King produced pop smashes for JAY Z and Eminem—but the heart of his work harks back to hip-hop's golden era. As part of the New Jersey-based Flavor Unit, his powerful soul and funk-sampling productions bedded raps by Queen Latifah, Latee, and Chill Rob G, while he can also claim revered tracks with Rakim and Gang Starr. A curio with David Bowie rounds out the mix.
