The great grandaddy of all horrorcore rap, Gravediggaz' 6 Feet Deep fused the skewed, dusty funk of Wu-Tang onto Addams Family organ and a lyrical prediliction for horror theatrics, although in contrast to what followed, many of the songs are tongue-in-cheek, goofy, and digressive. Containing two members of hip-hop veterans Stetsasonic and RZA from the newly-famous Wu-Tang Clan, plus the late Poetic, they initially formed after being screwed by Tommy Boy records in various ways. What at first was a one-off spleen venting became a movement in underground hip-hop, with a legion of horror obsessed freaks taking to the 808 and mirroring the rise of underground death metal in the early and mid-nineties. I've made a little game lately of comparing landmark albums in the respective genres; let's call this one Mental Funeral.
