Excellent and extreme Sydney act with a sound encompassing death, black and industrial elements that bares closest comparison to Zyklon. The band evolved from an earlier act called Crucible of Agony although almost no one from that band is involved in The Amenta anymore. Members are drawn from several well known Sydney bands, but exactly who they are is deliberately obscure, although it is known that Diazonon is Dave Haley from Psycroptic. The band's debut album was released through Listenable in 2004.
