MF DOOM’s debut album OPERATION: DOOMSDAY was originally released in 1999. It has seen at least two different versions on different labels, gone in and out of print, bootlegged, and even released once with a cheap scan of the original cover.  This is the first complete & remastered version of OPERATION: DOOMSDAY, containing the original album, alternate versions, b-sides and instrumentals – 42 tracks total – with all new artwork.

Following the CD/Lunchbox release and digital release, we held off announcing the vinyl until we were able to absolutely confirm a release date: June 21, 2011.  This is a release of Metalface Records.  Artwork by Jason Jagel, art direction by Jeff Jank.

Vinyl Box Set Contains:
4 RECORDS: The album, the instrumentals, b-sides, alternate versions.  Tin box with four records protected by paper dividers and cushioned inner box, as seen in the photos below.
LYRIC BOOK: In large 7×7-inch format, 32 pages.
CARDS: The 10 Doomsday MC card set.

The weight is a hefty 3.5 lbs.
