Genre: Hip Hop/Rap
Gravediggaz is an American hip hop group from New York City, known for its dark sense of humor and abrasive, menacing soundscapes. The group was formed in 1993, bringing together Prince Paul (The Undertaker), Frukwan (The Gatekeeper), Too Poetic (The Grym Reaper) and RZA (The Rzarector). It came about largely due to the efforts of Prince Paul. The group pioneered the small hip-hop subgenre of horrorcore.
The group's first album was originally to be titled Niggamortis; however, this potentially risqué title was changed to 6 Feet Deep for the American market (European versions of the album retained the original title, and also included the bonus track "Pass the Shovel"); it was released on August 9, 1994.
