Sadus is an American thrash metal trio from Antioch, California.
Sadus was formed in 1984 in Antioch, California. While their very first efforts were influenced by early thrash metal bands, such as Slayer, the band would later develop its own musical style by adding complicated chord progressions and constantly changing time signatures.
Their name was suggested by a friend of the band named Rick Rogers in 1985. It was originally taken from the novel Dune where Sadus are judges. The Fremen title refers to holy judges, equivalent to saints. However, according to bass guitarist/vocalist Steve DiGiorgio: "He (Rogers) liked the sound of it and he said he could make it into a cool logo. So we chose it [...] it's not supposed to have a meaning as we don't stand for anything."
