About
Agressor was a seminal underground thrash and death metal band formed in Milwaukee, Wisconsin, in 1986. They were a cornerstone of the burgeoning Midwest extreme metal scene during the late 1980s, known for their aggressive and raw sound. The band released several cult-classic demos, most notably 'Proclamation of Death' (1987) and 'The Order of Chaos' (1990), which featured vocalist Bill Steingraber. Though they never released a full-length studio album during their original run, they remain a highly respected name in Milwaukee's heavy metal history and are often included in archival compilations of the era's underground music.
