Madvillain is the moniker and stage name for the underground hip-hop collaboration between MF DOOM (MC) and Madlib (producer). Their debut album Madvillainy was met with critical acclaim for its unique approach - short songs, obscure lyrics, few choruses and a sound which was generally unfriendly to commercial radio. This was directly opposite to the formulas of popular hip hop of the time. The album features a host of guests from stones throw including MED, Wildchild and DOOM/Madlib aliases Viktor Vaughn and Quasimoto respectively.
