Break the Curse is a 1990 demo album by the Australian Christiandeath metal band Mortification. It was re-released in 1994 as Break the Curse 1990. The album focuses on Mortification's thrash metal style rather than their later death metal. Several of the album's songs were re-recorded for other Mortification albums. It was re-released on Rowe Productions in 2001 with updated artwork, an updated album booklet, and remastered audio. The album was re-released on Roxx Records as Break the Curse 1990–2010: 20th Anniversary Gold Edition in 2010 as a two-disc set with a CD containing bonus tracks and a DVD containing footage from Mortification's first crossover concert on 15 June 1990 at Harvest Centre in Melbourne, Australia, and later on vinyl as Break the Curse 1990: 25th Anniversary in July 2015. In 2022, the album was re-released as Break the Curse on Soundmass with remastered audio and a second disc containing the audio from the 2010 DVD.
Break the Curse was recorded in April 1990 while vocalist/bassist Steve Rowe, drummer Jayson Sherlock, and guitarist Cameron Hall were in the Australian Christian metal band Lightforce. Recording sessions took place at Oasis Studios in Melbourne and Timbertop Recording Studios in Ringwood, Victoria. The original version of Break the Curse was a cassette tape-based demo with six songs. The band was renamed to Mortification shortly afterward. On Mortification's self-titled debut studio album, the song "Infectious Growth" was renamed "The Destroyer Beholds".[4] In November 1993, the demo was remastered by Doug Saunders at Toybox Studios in Northcote, Victoria, and four more songs were included.
