In 1992, four guys stopped all the other rapping and producing they were doing, got together and quietly released one of the greatest hip-hop albums of all time.
Gravediggaz consisted, at least initially, of the Wu-Tang Clan's RZA, Prince Paul, Frukwan and the sadly-deceased Poetic. The group's 1994 album 6 Feet Deep (which, outside the US, was sometimes called Niggamortis) somehow manages to be both dark and constantly funny throughout. This track, Diary of a Madman, is taken from the album, but other standouts include 2 Cups of Blood and Defective Trip.
Gravediggaz released two more albums, 1997's The Pick, the Sickle and the Shovel and 2002's Nightmare in A-Minor. The latter featured neither Prince Paul nor the RZA, and Poetic died of colon cancer in 2001 before it could be released.
