Sadus is an American thrash metal band from Antioch, California, active from 1985 to 2015, and reunited in 2017. Originally a quartet, the band's sound fuses thrash metal with death metal, featuring highly technical musicianship. They are known for the unique death growl of vocalist Darren Travis, and bassist Steve Di Giorgio. During their career, Sadus has released five studio albums, one compilation album and four demos, and had only one lineup change, when guitarist Rob Moore left the band in 1993; instead of replacing him, the band continued as a trio. History Formation, early albums and split with Rob Moore (1985–1993) Sadus was formed in 1985 by vocalist Darren Travis, guitarist Rob Moore, bassist Steve Di Giorgio and drummer Jon Allen. A year later, the band would release their demo tape D.T.P. (Death to Posers). These sessions led directly to the inclusion of two tracks on the 1987 Raging Death compilation album. Quick to capitalize on this achievement Sadus stuck their hands in their pockets to self finance the debut album pulling in Metal Church guitarist John Marshall as producer. The pace of progress was quickened as a deal with label Roadrunner Records was secured resulting in a further album Swallowed in Black and touring with the likes of Sepultura and Obituary. Sadus was put on hold for 1991 as Di Giorgio opted to assist Death for their Human album. With this added exposure Roadrunner re-released the Illusions debut retitled Chemical Exposure as Sadus regrouped for a summer American tour opening for Morbid Angel. Although a further album for Roadrunner, 1992's A Vision of Misery, resulted in a European headline tour, Sadus found itself labelless upon their return. Further setbacks occurred when Di Giorgio was enticed back to Death for the Individual Thought Patterns album and a subsequent year-long bout of touring. Di Giorgio was to return for club shows with Sadus but before any momentum could be gained Moore bailed out. Sadus as a trio, Elements of Anger and hiatus (1993–2005) Instead of replacing Moore, Sadus continued as a trio crafting the Scott Burns produced Elements of Anger in 1997. The in demand Di Giorgio, along with drummer Jon Allen, also operated a side project Dragonheart (later Dragonlord) with former Vicious Rumours and present day Testament guitarist Steve Smyth and his fellow Testament six-stringer Eric Peterson. Di Giorgio teamed up with Iced Earth in late 2000. News during
