The experimental 1980s saw the emergence of thrash metal music characterised by heavy distortion, pinch harmonics, and whammy bar abuse. Polish representatives of this particular music genre are Silesian Kat & Roman Kostrzewski band, Acid Drinkers from Poznan, and Vader, death metal band from Olsztyn. Quo Vadis, the death metal band from Szczecin will be making a special guest appearance at the concerts. The bands will be performing in four Polish cities: Gdańsk (26/09), Warsaw (27/09), Wrocław (28/09) and Kraków (29/09).
