30 years ago – on 13 August 1991 – the legendary Witches' Cauldron in the legendary Chorzów Śląski Stadium was visited by a one-of-a-kind musical cavalcade. For the first time in the history of Poland, the country was visited by such a great musical production. It was also the first time that the legendary band AC/DC appeared in Poland. But not alone, but with Metallica, who were at the peak of their form, and Queensryche. In Poznań's U Bazyla club, this historic event will be recreated – 4 Szmery and Alcoholica will play the exact setlists of AC/DC and Metallica from August 13th, 1991.
