On this day August 9, 1984, Iron Maiden made history by kicking off their groundbreaking “World Slavery” tour in Warsaw, Poland. This tour was not only monumental for the band but also for the world of rock music, as it marked the first time a Western band performed behind the Iron Curtain, the symbolic boundary dividing Europe between the Soviet Union and the West. By bringing heavy metal to an audience that had been largely isolated from Western music, Iron Maiden’s performance was a powerful moment of cultural exchange, showing the unifying power of music across political divides.
