I'm sure someone, at some point has mentioned the Gravediggaz, but I'm not looking through this whole thread.
Anyways, the Gravediggaz are a mighty fine rap group, members are:
Rzarectah more commonly known as the RZA, a hip hop legend, and member of the greatest rap group of all time, Wu Tang Clan. A very crazed flow as part of the GD's, delves into darker subject matter, and paints a very gruesome picture with his grimey lyrics.
The Gatekeeper More commonly known as Frukwan. Has the wildest flow since ODB, the man comes in on a beat, takes a shit all over it, says some shit you can't understand, and leaves you with a lasting impression, if I hadn't of given info, i guarentee someone would have been like "who was the crazy guy?".
Grym Reaper More commonly known as Too Poetic, usually a very smart, poetic (pun intended) MC but as part of the Gravediggaz, he's grimey as fuck, like the others he dives into deeper subject matter, and changes a lot of things about his style, unfortunately, Too Poetic passed away of cancer (colon i believe) earlier this year.
The Undertaker (cool name, huh?) More commonly known as Prince Paul, this guy doesn't rap, but he makes some of the dopest beats to ever grace the hip-hop landscape, from his work in De La Soul, to his work as the Undertaker, to his work everywhere else, this man has produced countless classics.
These guys are true pioneers of the sub genre knows as "horrorcore", horrorcore is known for its gruesome tales of violence, death, killing, and whatnot. However, this isn't your typical ICP violence bullshit rap, it's highly skilled MC's spitting crazy lyrics about exremely dark and violent stuff.
Unfortunatley, a death among the group, and the fact that the group was already splitting has ensured we will never hear a new Gravediggaz song (not with all the members) and they only had the chance to release a few albums. These albums include:
6 Feet Deep This is IMO their best album, every song on here is a classic, this is a must hear for any Hip Hop fan.
The Pick The Sick And The Shovel This one isn't too far behind 6 Feet Deep and is also a classic album.
Nightmare in-A-Minor This album doesn't include any input from RZA or Prince Paul as both members had left the group by then, Too Poetic died, so these songs, and this album are basically the last project he worked on during his death, a highlight of this album is the song "Burn Baby Burn" in which Poetic talks about his terminal illness and coming to grips w/the fact he knows he's gonna die, it's truly a sad, yet great song from yet another fallen MC.
So yea, check these guys out if you get a chance, these guys are legends in the Rap game and these albums are required listening for any true rap fans out there.
