Formed in 1984, Messiah played a major role in the development of thrash and death metal in Switzerland. They released two groundbreaking albums on Chainsaw Murder Records: Hymn To Abramelin in 1986 and Extreme Cold Weather in 1987. In the early nineties, Messiah signed a contract with Karl Walterbach's label Noise Records, on which three more albums were released: Choir Of Horrors (1991), Rotten Perish (1992), and Underground (1994). Many consider Choir Of Horrors to be the highlight of Messiah's work. This 35th Anniversary edition includes live recordings (Switzerland 1992, Erlangen and Berlin 1993) as well as the album's pre-production, including the unreleased track "Indecent Assault Of The Tribe."
