Disavowed was formed as Nocturnal Silence in the summer of 1994. A few shows were played and a demo entitled Into The Abscess was recorded in 1995. The band manages to sell and give away 150 copies. Another demo called ...And Create A Moonless Sky was recorded for which Pyaemia singer Joel Sta recorded some vocals. Shortly thereafter drummer Maarten Winnips quits and is replaced by Pyaemia's Robbert Vrijenhoek. When guitarist Dorus Neijboer quits also, Sta replaces him and officially joins the fold. Following the line-up changes, the band's style turns heavier and in the May of 1998 a demo CD entitled Plateau is released. The band has now changed monikers. The demo Point Of Few follows in December of 1999. The band signed with Unique Leader Records (Pyaemia is already contracted here) and released Perceptive Deception in late 2001. The album was recorded at Excess Studio. The band toured North America and plays Germany's Fuck The Commerce Festival to promote its debut.

Robbe Vrijenhoek was forced to withdraw due to a recurring wrist injury. Obsidian, featuring new singer Robbe K of Disavowed, signed to Rusty Cage Records. The group finally issued a second album in 2007 after several line-up changes. Gerben also joined Obsidian in late 2007. The band recruited drummer Morten Løwe Sørenson (Submission, Scarve, The Cleansing, etc.) as of April, 2009.
