Sadus was an American thrash metal band from Antioch, California, active from 1984 to 2015, and again from 2017 to 2021. 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 run, Sadus had 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 would continue as a trio until their disbandment in 2021.
