Operation: Doomsday

Operation: Doomsday is the debut solo album by Daniel Dumile, his first full-length under the MF DOOM moniker. It was released as CD & 2/LP by Fondle 'Em Records on January 5, 1999. The album was reissued in 2001 on Sub Verse Records in 2001 with a slightly altered track listing.

Despite being reissued, the CD went out of print sometime between 2003 and 2004, quickly becoming an expensive collector's item, while the LP stayed in print for much longer.

The album was released on iTunes in May 2007 and widely re-released on Dumile's Metal Face Records on October 7, 2008.

It was also reissued by Stones Throw Records in 2011 as Operation: Doomsday (Complete)  with cover art design by Jason Jagel, who also did the art for MM.. FOOD. It was reported that there were licensing issues with the original artwork that caused problem with reissuing.
