KMD (Kausing Much Damage, or A positive Kause in a Much Damaged society) was an American hip hop trio active in the early 1990s. The core of the group was composed of brothers Daniel "Zev Love X" and Dingilizwe "DJ Subroc" Dumile. The group is best known for launching the career of Zev Love X, who later became MF DOOM. The group's original third member, Rodan, left before the group signed with Elektra Records; he was replaced with Onyx the Birthstone Kid. The group disbanded in 1993 after the sudden death of DJ Subroc and the subsequent decision by Elektra to drop the group from their label.
KMD released two studio albums, Mr. Hood (1991) and Black Bastards, with the latter originally recorded in 1993 but not officially released until 2000 due to its cancellation by Elektra.
