Sadus is an American thrash metal band from Antioch, California, active from 1984 to 2015, and again since 2017.Originally a quartet, they are known for the unique, borderline death/black metal growling of vocalist Darren Travis, and speeding up thrash metal to levels previously unheard of with the help of bassist Steve Di Giorgio whose bass lines truly pushed the limits of the genre.Over the course their 0-year 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 has since continued as a trio.
