In the sweltering excitement of September 1991, Metallica graced the Tushino Air Field in Moscow during a pivotal moment of their career, just after the release of their iconic self-titled album, commonly known as "The Black Album." This album, which dropped just a few weeks earlier in August, marked a significant turning point for the band—transitioning from underground thrash metal legends to mainstream rock giants. The live performance of "One" in Moscow not only showcased their growing popularity but also emanated electric energy fueled by the historic backdrop of a post-Soviet Russia. Metallica was part of a massive free concert attended by an estimated 1.6 million people, illustrating their profound impact during a time of unprecedented change. This performance captured the raw emotion and power of their music, leaving an indelible mark on both fans and history. It’s fascinating how they turned a simple song about war into an anthem that resonated worldwide amid a landscape of liberation.
