DANGERDOOM was a musical collaboration between producer DJ Danger Mouse and rapper MF DOOM. Their first album, The Mouse and the Mask, was released in 2005, and followed by the Occult Hymn EP, available for free download from the Adult Swim website.
The Mouse and the Mask was released on October 11, 2005 by Epitaph in the United States. It was also released by Lex Records in the United Kingdom on October 17, 2005, with different cover art.
It was inspired by Cartoon Network's Adult Swim programming (where it also received considerable advertising) and features guest performances by Ghostface Killah, Cee-Lo and Talib Kweli as well as character voices and clips from many Adult Swim shows.
DANGERDOOM have also recently released the "Occult Hymn" EP. It features two skits, reworkings of several tracks from "The Mouse and the Mask", and is available for free download from http://www.adultswim.com/promos/dangerdoom/occulthymn/index.html.
