Monster is the tenth studio album by the German band Oomph!. The band held a contest for fans to create the cover art for the album, similar to the contest for Korn's album Issues. The winning artwork was chosen by the band and presented on Oomph!'s MySpace page on 23 July 2008.
The first single, "Wach auf!", was released early in 2008 as a promo for the movie Aliens vs. Predator: Requiem. The video for the second single, "Beim ersten Mal tut's immer weh", was released on 14 July 2008. The video for the third single, "Labyrinth", was released on 12 August 2008. A video for the fourth single, "Sandmann", was released on 9 January 2009, while in-between an additional video for the song "Auf Kurs" was released on 12 November 2008. A reissue of the album was later released featuring "Sandmann". The album was uploaded onto the band's MySpace page in its entirety on 14 August 2008.
