Formed in 1988, Aggressor were one of the most extreme acts in the Polish scene, initially featuring Piotr \"Piecia\" Peichert on vocals, Paweł Wirkus on drums, Stanisław \"Menel\" Jocz on guitars and Beni \"Wujek\" Gałązka on bass. After playing some concerts in their home city of Słupsk, Wirkus was replaced by Willi. A second guitar player, Robert \"Broda\" Kowalczyk was incorporated as well. The same year they recorded their first demo and went on tour in Poland, appearing at festivals like Drrrama and Sthrashydło. They later experienced more line-up changes with the addition of Piotr \"Piecia\" Peichert and Henryk Kubała. This formation recorded a second demo tape entitled Notoric Drinkers.
With 2 demos behind them, Aggressor shared stage with other underground metal acts like Vader, Wolf Spider and Turbo – recording a third one, Still Delirium in 1990. The band subsequently suspended its activities due to the member's drinking problems.
Aggressor resurrected in mid-2004, featuring a new drummer Piotr \"Zwierzak\" Owerko and new guitarist Oskar \"Szoszon\" Tyndorf – they began working on new material, in December performing the first concert since the band's early 90’s hiatus. 4 Years later, they released Live Eternally, which was recorded at the Replica-Art Rec. in Słupsk. Crisis, published in 2010 and Death Follows Me in 2013 complete Aggressor's current discography.
