Omen is the fourth studio album by the Norwegian Christian extreme metal band Antestor, released by Bombworks Records on November 16, 2012. Recording began in 2011, and was mostly conducted at the home of vocalist Ronny Hansen. The album cover is a painting by Polish artist Zdzisław Beksiński, and depicts a deformed, many-fingered humanoid creature playing a trumpet. Antestor met with critical praise for its musicianship and the progressive sound on the recording. Critics described the sound as primarily black metal, though the band prefers the more general term "extreme metal" to describe the sound on Omen.
