6 Feet Deep (also titled Niggamortis in some regions) is the debut album of the American hip hop supergroup Gravediggaz. Formed by former Tommy Boy Records artists Prince Paul, RZA, Frukwan and Poetic, the group utilized horror-themed imagery and lyrics combined with black comedy and satire to vent their frustrations with the hip hop record industry. The album's concept satirizes the hardcore hip hop and gangsta rap of the early 1990s. Released on August 9, 1994 by Gee Street Records, the album helped usher in horrorcore.
